When it comes to air filters, K&N Engineering know a thing or two.

Founded in Riverside California by Ken Johnson and Norman McDonald (K&N), this dynamic outfit began as a supplier of motorcycle parts, and a factory race team supporter, before migrating into the world of high-performance air filtration systems.

K&N used their extensive motoring knowledge to develop reusable air filters for race cars and heavy duty vehicles such as SUV’s, snowmobiles and 6-8 Class trucks – and it didn’t take long for them to make a pretty colossal name for themselves with their high-quality innovations.

Today, K&N are producers of the world’s best performance air filters and their mission statement is simple:


“To Provide a High Performance Experience for our Customers and Ourselves”.


This philosophy is something that Ken and Norm have maintained since day one, and this certainly shows in their latest engine based air filtration offerings…


Replacement Filters

K&N’s modern replacement air filters are designed to improve engine performance without modifying your intake system. These nifty filters fit directly into your Original Equipment air box and are completely washable and reusable. Here are a few more of their features:

  • Hard wearing, long lasting and environmentally friendly
  • Mild horsepower increase
  • Exceptional filtration and dependable protection for long engine life
  • Good for high-performance filtration of up to 50,000 kilometers at a time (depending on conditions)


Performance Upgrade Filters & Cold Air Induction Kits

K&N’s performance enhancing filters are a force to be reckoned with, especially if products like their 57i Gen II are anything to go by. These high-spec filters replace a motor’s original air box and reduce intake restrictions to increase engine power, performance and resonance (it makes the engine sound sweet!). Key features of the 57 and Typhoon series kits include :

  • Increased engine horsepower – guaranteed
  • Low restriction, custom made pipework
  • Large capacity hi-flow reusable cone filters

Their passion and dedication to the motoring industry has kept them at the top of their game since the 1960’s, and with a proud legacy as long as Route 66 itself, it’s safe to say that when it comes to high-performance air filtration products, you’re in great hands.
