Hey guys I just wanted to get your opinions on the K&N flame arrestors? There is quite a bit of mixed info from what info I could find and it wasn’t anything directed toward big blocks or performance boats mainly 4.3’s.
Anyway, I have a tiny little flame arrestor on my boat that I know in fact is choking it out. So bad I have to run it without it which I’m not comfortable running no flame arrestor. And yes I have cleaned it. I am in between just getting a larger flame arrestor from cpperformance for around $70 or deciding if it’s worth the extra $50 or so for a K&N. I have run them on vehicles before and do not care for them on fuel injection cars whatsoever I have always had trouble with them causing hard starts. But on a carved boat I would be willing to spend the money and give it a try if it’s a better suit.
