BMW 320i e36 with K&N stock replacement air filter
Perfect sound, instant reaction.

Hi Guys from the UK,

My son has installed K&N filters on his last few cars and is always singing its praises. He first experienced these amazing filters when he worked at the famous Silverstone Race Circuit in the UK. Well, he 'demanded' I install one on my beloved BMW convertible. The first thing I noticed was the fantastic noise then I experienced the power. I was very impressed.

My son has a BMW E36 2.8i Coupe and has filter with heatshield [ mine does not have this]. Just to prove a point he installed his filter with shield in my car yesterday and we took it for a test drive. I simply could not believe the amazing amount of extra pulling away power I had at 2500rpm - it was awesome!!!

So much so, that now I am in the process of having a K&N Apollo CIS filter fitted whilst having the car super chipped. So, between the both I am hoping that my car will have an amazing new lease of life. 'Boy-racers' just admire my lovely rear end when I leave them to simply ponder the question at the lights "what on earth has that lady got under her bonnet"!!!

Am recommending to all our colleagues who love and respect their cars. I shall install my old filter into my daughter's car - she needs to be converted also!

I have always used K&N air filters on all the vehicles I have owned.  Fitting a K&N air filter is the simplest and easiest way at instantly jumping up the enjoyment you get from driving your vehicle.  My latest vehicle is a BMW 320i 1992 E36.  I drove it around for four painful months with the standard paper filter and then the day came when I installed the K&N replacement panel filter.  Wow!!  What an immediate difference.  Now my BMW 320i feels more like a 325, very lively and responsive! I almost have to learn how do drive my car again.  The increased power and mpg are amazing from such a simple product.  My BMW now feels like a weird horse trying to leap forward at every opportunity.  Torque from low down revs right up to red line has jumped right up!  Cruising around, overtaking, off the lights and motorway driving have improved more than I thought possible!  My BMW 320i is now sheer pleasure to drive everyday!  Thanks K&N you have totally transformed my BMW 320i from a tame coupe into a very sporty coupe with improved fuel economy of up to 7-10% !!!  My K&N replacement panel filter will pay for itself within the next few months!!

Thank you,
Charlie, London, United Kingdom
