K&N High-Flow Performance Air Filter for Harley-Davidson Sportster (2004–2013)

Experience a significant boost in V-Twin performance with the K&N High-Flow Air Filter, specifically engineered for 2004–2013 Harley-Davidson Sportster models. Designed for riders who demand more from their 883cc or 1200cc Evolution engine, this premium air filter replaces the restrictive factory paper element with race-proven filtration technology. By maximizing airflow volume, K&N helps your “Sporty” achieve crisper throttle response, improved acceleration, and the measurable horsepower gains needed for both city carving and highway cruising.

High-Flow Cotton Gauze Filtration Technology

The K&N HD-8834 features four to six layers of surgical-grade oiled cotton gauze media, pleated between epoxy-coated aluminum wire mesh. This advanced construction creates a massive surface area that allows for low-restriction airflow while maintaining filtration levels critical to engine longevity. Unlike standard filters that act as a barrier, K&N’s deep-pleat design traps harmful dust and debris within the media layers, ensuring your Stage 1 intake remains efficient even as it accumulates miles.

Washable and Reusable “Lifetime” Filter

The K&N replacement air filter is a sustainable, cost-effective upgrade that is designed to last the entire life of your motorcycle. It is completely washable and reusable, requiring cleaning only every 50,000 miles under normal street riding conditions. By using a K&N Recharger kit, you can easily restore the filter to like-new performance, eliminating the need for expensive disposable paper filters. Every unit is backed by K&N’s legendary Million-Mile Limited Warranty, making it the ultimate Harley-Davidson maintenance solution.

Direct OEM Fitment – Replaces Part #29331-04

Engineered as a precision drop-in replacement for Harley-Davidson OEM #29331-04, this filter requires no custom fabrication, fuel re-mapping, or permanent modifications for a standard setup. It fits perfectly inside your factory oval air cleaner housing. Fitment is confirmed for the following Sportster models:

  • Iron 883: XL883N (2009–2013).
  • Forty-Eight: XL1200X (2010–2013).
  • Nightster: XL1200N (2007–2012).
  • Sportster Custom: XL883C and XL1200C (2004–2013).
  • SuperLow: XL883L (2011–2013).
  • Note: Not compatible with XR1200 models or Screamin’ Eagle aftermarket backing plates.

The Essential Stage 1 Foundation

For riders looking to build a Stage 1 performance kit, the K&N High-Flow Air Filter is the critical first step. While it provides an immediate improvement in engine clarity on its own, pairing this filter with a high-performance exhaust and an EFI fuel tuner (such as the Vance & Hines FP3 or FP4) will unlock the full torque and horsepower potential of your Evolution engine. The improved laminar airflow ensures your engine runs cooler and more efficiently, even during spirited riding.

Simple DIY Installation

Upgrading your Sportster air intake is a 10-minute task that requires only basic hand tools. The K&N HD-8834 features a durable, flexible frame and a precision-molded sealing bead to ensure a 100% airtight fit against the throttle body or carburetor. This prevents “dirty air” bypass and ensures your engine receives only the cleanest, highest-velocity air possible.

Stop settling for restrictive airflow. Upgrade to the K&N High-Flow Air Filter today and experience the ultimate in Sportster performance!

K&N High-Flow Performance Air Filter for Harley-Davidson V-Rod (2002–2017)

Elevate the performance of your liquid-cooled Revolution engine with the K&N High-Flow Air Filter, specifically designed for the 2002–2017 Harley-Davidson V-Rod series. As a motorcycle built for high-RPM power and drag-inspired speed, the V-Rod requires a massive volume of clean air to perform at its peak. This premium Stage 1 air filter upgrade replaces the restrictive factory paper element with K&N’s race-proven filtration technology, delivering increased horsepower and torque for your VRSCA, VRSCB, Night Rod, or V-Rod Muscle.

Advanced Cotton Gauze Filtration for Maximum CFM

The K&N HD-1102 utilizes multiple layers of surgical-grade oiled cotton gauze media pleated between epoxy-coated aluminum wire mesh. This unique design allows for high-velocity laminar airflow with significantly less restriction than standard filters. By increasing the CFM (Cubic Feet per Minute) of air reaching your throttle bodies, this filter provides the oxygen-rich intake necessary for crisper throttle response and smoother acceleration throughout the entire powerband of your 1130cc or 1250cc Revolution engine.

Washable and Reusable “Lifetime” Engineering

The K&N V-Rod air filter is a sustainable “lifetime” product, meaning it is the last air filter you will ever need to buy. Unlike disposable paper filters that quickly clog and lose efficiency, this washable and reusable filter can be cleaned and re-oiled using a K&N Recharger service kit. It is designed to go up to 50,000 miles between cleanings under normal street conditions. Every filter is backed by K&N’s famous Million-Mile Limited Warranty, ensuring your high-performance cruiser is protected for the long haul.

Direct Drop-In Fitment – Replaces OEM #29437-01

Engineered as a precision drop-in replacement for Harley-Davidson part number 29437-01, this filter requires no custom fabrication or permanent modifications to your bike. It features an application-specific base seal and sealing bead that ensures a 100% airtight fit within the stock V-Rod air box. Fitment is confirmed for the following VRSC models:

  • VRSCA / VRSCB: Original V-Rod models (2002–2006).
  • VRSCD / VRSCDX: Night Rod and Night Rod Special (2006–2017).
  • VRSCF: V-Rod Muscle (2009–2017).
  • VRSCR: Street Rod (2006–2007).
  • VRSCX: 10th Anniversary and Special Edition models.

Why Choose K&N Performance?

To unlock the full potential of your V-Rod performance intake, we recommend pairing the K&N filter with a high-performance exhaust system and a fuel management tuner. Because the Revolution engine is highly sensitive to air-fuel ratios, increasing the airflow with a K&N High-Flow element allows for more aggressive tuning, resulting in a cooler-running engine and maximum top-end horsepower gains. This is the foundation of any professional-grade Stage 1 build.

Fast and Easy Installation

Upgrading your Harley V-Rod air intake is a simple DIY project that can be completed in minutes. By simply removing the airbox cover (dummy tank) and swapping the stock element for the K&N performance filter, you provide your engine with an immediate performance boost. The filter arrives pre-oiled and ready to ride, so you can get back on the road and feel the difference in power delivery instantly.

Legendary Cotton Gauze Filtration Technology

The secret to K&N’s success lies in its unique high-flow cotton gauze media. Unlike paper filters that can “choke” your intake as they get dirty, the K&N HD-1614 features four layers of surgical-grade cotton pleated between aluminum wire mesh. This design provides a massive surface area for low-restriction airflow while maintaining excellent filtration levels critical to engine life. Whether you are cruising the interstate or navigating city traffic, this filter ensures your Harley is always breathing the cleanest, highest-volume air possible.

Washable and Reusable “Lifetime” Filter

The K&N replacement air filter is likely the last air filter you will ever need to buy for your bike. Designed to be washable and reusable, it can be easily cleaned and re-oiled using a K&N Recharger kit, restoring it to like-new performance every time. This eco-friendly design saves you money on Harley-Davidson maintenance costs over the long term and is backed by K&N’s famous Million-Mile Limited Warranty. It is a rugged, sustainable choice for the high-mileage touring rider.

The Ultimate Stage 1 Intake Upgrade

For riders looking to complete a Stage 1 performance kit, the K&N High-Flow Filter is the essential foundation. While it works perfectly with a stock exhaust, pairing this filter with high-flow slip-on mufflers and an EFI tuner (like the Vance & Hines FP4) will maximize your torque and horsepower gains. The improved laminar airflow provided by K&N allows your engine to run cooler and more efficiently, even under the heavy loads of two-up touring with loaded saddlebags.

Easy 5-Minute Installation

Upgrading your Harley air intake is a simple DIY task. The K&N HD-1614 features a durable, application-specific sealing bead that ensures an airtight fit within the stock air box, preventing unfiltered air from entering the throttle body.

K&N High-Flow Performance Air Filter for Harley-Davidson Twin Cam (1999–2015)

Unlock your engine’s hidden potential with the K&N High-Flow Air Filter, the gold standard for Harley-Davidson performance tuning. This precision-engineered intake element is specifically designed for 1999–2015 Twin Cam models, providing a massive boost in airflow volume compared to restrictive factory paper filters. By optimizing the air-to-fuel ratio, K&N helps your 88ci, 96ci, or 103ci engine deliver smoother acceleration, sharper throttle response, and measurable horsepower and torque increases across the entire RPM range.

Proven Cotton Gauze Filtration Technology

At the heart of every K&N air filter is four layers of surgical-grade oiled cotton gauze media. Unlike standard filters that trap dirt on the surface and quickly clog, K&N’s deep-pleated design utilizes a “depth filtration” method. This allows the filter to trap microscopic particles while maintaining low-restriction airflow, even as it accumulates road grime. This is the ideal Stage 1 intake upgrade for riders who want high-output performance without compromising engine longevity or protection.

Washable, Reusable & Eco-Friendly

Stop wasting money on disposable filters. The K&N replacement air filter is a “lifetime” product that is completely washable and reusable. Under normal street conditions, this filter can go up to 50,000 miles before requiring its first cleaning (using a K&N Recharger kit). This sustainability makes it a smart investment for Harley-Davidson maintenance, as it is designed to last the entire life of your motorcycle. Every filter is backed by K&N’s famous Million-Mile Limited Warranty for total peace of mind.

Direct OEM Fitment – Replaces Part #29461-99

This high-flow intake element is a direct replacement for Harley OEM part number 29461-99 (and 29400042). It is designed to be a “drop-in” fit for the stock oval “football” style air cleaner housing found on:

  • Harley Touring (1999–2007): Road King, Street Glide, Electra Glide, and Ultra Classic.
  • Harley Softail (2000–2015): Fat Boy, Heritage Classic, Deluxe, Slim, and Breakout.
  • Harley Dyna (1999–2017): Street Bob, Low Rider, Super Glide, and Wide Glide (select models).
  • Note: Not compatible with Screamin’ Eagle or aftermarket “Big Sucker” backing plates.

Maximize Your Stage 1 Performance

To truly feel the V-Twin power gains, we recommend pairing the K&N High-Flow Air Filter with a high-performance exhaust system and a fuel management tuner like the Vance & Hines FP4. By increasing the oxygen intake, your EFI system or carburetor can optimize combustion, resulting in a cooler-running engine and more aggressive sound. Whether you are daily commuting or crossing the country, K&N provides the laminar airflow necessary for a high-performance riding experience.

Simple DIY Installation

Upgrading your Harley-Davidson air intake is one of the easiest maintenance tasks you can perform. With basic hand tools, you can swap your old paper filter for a K&N performance element in less than 10 minutes. The filter features a durable, precision-molded frame and an application-specific sealing bead to ensure an airtight fit against the throttle body, preventing “dirty air” bypass and protecting your cylinder walls.
