Customer Feedback

I just bought a lightly used 2005 Acura MDX and one of the first things I did within my first week of ownership was put the stock replacement K&N air filter in the air box.  I had one in my previous car a 98 VW GTI VR6.  The K&N air filter is an absolute no brainer.  Do not wait any longer this is a decision that will turn out to be one of the best decisions you have ever made, and it's so simple and affordable.  

If you know your car... You can hear her finally breathing freely like she has always dreamed of.

...and yes it's true.  All of your stats will improve instantly, better gas mileage, and more horsepower.

I am a dedicated K&N owner for life (I'm only 30), and I do almost nothing else to my own cars, they go to the dealer or a certified shop for everything else, but this is so simple you would have to be foolish not to try on your own.  

Remember to google yourself some pointers on opening your factory air box properly if you need to.

The whole process took me about 15 minutes.

The best $40-$60 you will ever spend.

I installed the system on my Opel Omega B and I was quite impressed from the intake. The power has had a tangible increase. I recommend this intake system to all who are hesitating!!!

I put the 57i kit onto my Vauxhall Corsa 1.8 SRI 2004. It sounds great.
