When I installed my RiffRaff coolant filter I had clearance issues with the snorkel on the factory intake and battery box cap. I knew I would be replacing the intake and since it was pushing the coolant filter to the passanger side just a tad I took my dremel tool and cut away material to make room.

I am worried that with the Ford Ais or the S&B CAI I will have clearance issues and do not want to cut the snorkel on either one of these. I am wondering if I will have better luck with either one or should I just do the 6637 with the Donaldson blue filter? Sorry about the rotated picture, It always happens. Thanks guys

 

I prefer the 6637 filter intake kit. Been running it for almost 10 years now and it is great. Won't interfere with coolant filters either.

 

I think I will just get the 6637 from Clay with the Donaldson filter, it will give me more room to change the coolant filter. I really want the Ford AIS or the S&B but the thought of having to cut the snorkel stinks and kinda defeats the purpose.
