Hey, I'm new to this forum but I've got a question. I just bought a 04' Jetta GLS 1.8T off lease. I wanted to get more air without spending a lot and wanted it to be easy so I bought a K&N High Flow filter to replace my stock one. I've heard that they are bad for the MAF sensor but I've had it in for about 3 days now and it hasn't done a thing. Are these accusations true or false about them? Also, will a high flow filter increase gas mileage? If so by how much? Thanks

I duno about the gas mileage, but the filter shouldn't a do a thing. All it's doing is allowing a lil bit more air, that's all. I don't have a problem.

Yea but that defeats the purpose of "cold air". you are just sucking in hot air now that is swirling around the engine bay.

thats why i got a heat sheild, its a bad idea to have one of the cold air intakes that put the filter down by the wheel wells where i live cause ive had several friends (not in vw's) suck up water and mess their engines all up. and my frontmount cools the hell out of my charge air anyways
