Re: K&N Filters
I have K&N's in my cars. Hard to tell any performance improvement but you will save money in the long run by not having to replace the filter. Unless you are using the $2 cheapies, then it will take much longer to see savings.
I swear by them and I've had the panal filters in two of my vehicles. I DEFINATELY noticed fuel saving on the HW, and a slight increase in power which I will gladly take. I started a gas mileage thread on K&N in the lounge a month or so ago that you might like to read......
Yeah I'm familiar with Air Raid but thats not what I'm thinking of I knew of Green too but it just seems I read an article comparing different filters a while ago and there was a green filter on there but the company wasn't Green...
