I have a K&N 57i fitted to my esc cos small turbo,but i think its pretty pants actually.I was gonna put the original air box back on and put a uprated panel filter in it,or i was gonna try the pipercross viper kit.The thing is it's nearly £250 is it really worth shelling that much dosh out?..has anyone tried the viper kit?Your opinions on this matter would be appreciated.

 

Had a viper kit fitted to my small turbo cossie last summer just after I bought it. Did'nt have a power run on the car before the kit was fitted, but was knocking out 223 horses after which I thought was pretty good for the middle of summer

Had not had the car long so performance gains were hard for me to judge

I think there were better kits out there but not many would go on a small turbo model and all were just as expensive

Having said all that I would still have anything over the standard kit

 

ggr k+n dont know if yours is the same m8

 

That K+N is the daddy Id stick a good panel filter in your standard airbox unless your wanting mega power.The small turbos idle better and run better with the airbox on.

 

I sell these ones and they are
They also sound awesome.
I have one on my big turbo model (290bhp)
and here's one on a 559bhp one we done;
