I have a K&N laying around and I want to get rid of my JLT (tired of its poor fitment and general ugliness). I have a 90MM MAF, will I have any issues?
well, check and see how the MAF adaptor piece lines up with that MAF. if the adaptor has a smaller diameter then thats a no go. also check the piping that connects to the other side of the MAF and see if it's big enough to fit around it. you'll find out in no time.
also, you'll need to get retuned for that MAF, or at least have it checked out.
few guys have picked up another 8-10whp with full boltons, other have gotten less, guess it depends on the tuner. I got mine free, so it was a worth while swap.
