This filter is in my 2011 Jetta. I instantly noticed relief on the engine, way more air flow with little restriction. Best filter on the market and K&N is the only brand that I would suggest to put in your vehicle. Cabin filter, air filter, and oil filter.... K&N all the way . Plus, million mile warranty, can't beat that.

Instantly widened the peak HP range in my Rabbit and increased total HP and torque noticeably. Side-effects of this phenomenal air filter? It makes it much easier for your vehicle to accelerate, so I've lost some of my MPG. Had I more restrain, I don't expect this to be a factor.

I have had K&N filters in all my cars. They work and save you money. Better performance.

Instantly noticeable increase in pep, take-off and engine strain noise (reduced) in a high mileage VW Jetta that just had a new air filter placed 6 months previous. Second K&N filter owned on my vehicles and I cannot say enough positive about them. The hype is not an exaggeration.

I use K&N in all my autos(2008 Passat, 2010 Golf, 2010 F150, 2011 Pathfinder). Have for 20 years now, hands down the best filter on the market.
