Flame arrestor for 5.7 mpi

[jdubslopro]

I've looked all over and can't seem to locate a flame arrestor for my motor. It was a recent swap from a v6 2bbl to a 5.7 mpi. I currently have fashioned the 4.3 flame arrestor to fit over the throttle body including a piece of exhaust bellows and clamp, but I would like to use the right part. Serial #0M011557. I can't find a k&n replacement part, it looks like they only have them for the 5.7 tbi. Anyone have this motor and use a k&n? The throttle body od is just shy of 4" I believe.

Re: Flame arrestor for 5.7 mpi

Have you actually called them? Just looking at their site may not give you the right information.
Tell them the original part number for your Merc flame arrestor is 861443T and they might be able to look it up for you. Or you could use the OEM part.
