Hi ,im looking for info as i have just bought a k+n typhoon filter kit which goes in the wing,its for my uk 2003 wrx...but ive read some nasty stories about oil filters messing up a sensor...is there anyone who is using one of these or tried one of these......any help welcome....cheers

 

K&N use a dry filter so they are maf sensor friendly. Some other brands use an oil based filter which can effect the maf sensor as you mentioned

 

Unless your running silly bhp your better off with a good panel filter
