Wondering if anyone has put K & N's on 5.7 EFI's, I ordered two for my 28zx but the stock mercruisers have a flange,the two from CP Performance did not have the same flange so it would not sit on the carb. I have called several performance marines but have not located anyone that has something that will fit my application. I would appriciate any help locating aftermarket flame arrestors.

I installed a K&N flame arrestor/air filter on my 502 and I had to take off the stock flange. This came off very easily. Once this was removed the K&N filter bolted right up with no problem using the supplied four (4) bolts. Unfortunately I don't know what differences your 5.7 has on the intake compared to my 502.

Hey nails. Have you tried out the boat since the installation of you new tips? As you know, I don't have much information on K&N for your 5.7 EFI's. Will you be making it down to Lake of the Ozarks?

Have not tried the new tips, looking forward to going to the ozarks this weekend with you guys, should be a great time. I was told that I might need to look at adding a velocity stack to mount the K & N too, know anything about that?
