Heavy duty sizzors fix that edge.

Textured plastic. Does it help? Snorkel put back together and sealed with black rtv. Some sensors will be damaged from rtv so keep clear of car until fully dry. Reinstall whole mess after a quick hand sand to remove barbs of plastic and a good cleaning. Driving after, low end felt the same but seemed to pull better from 4000 rpm to 6000 rpm where the 8 speed shifted. It was also 88 degrees and much hotter than when I picked it up this morning. Seems he has already had someone remove the center mufflers. I did not know that this morning. Still quiet, too quiet for him. I will get feedback from the owner tomorrow.

You are doing very nice job on your projects!

It is just ridiculous how some people just say it's not worth any hp to modify (or fabricate a completely new design) factory air box, even if had a dyno graph showing clear gains.. no matter how crappy design the stock box was.

Clearly small things matter a lot, when combined.

I did some more research on this mill and the plastic intake could use some work as well. It is all sealed but I could see behind the throttle body it needed work. If he likes the results I will let him know we can do that next. Thanks, Charlie

Got a call from the car owner today and he is thrilled! He said on his way to work this morning a new 5.0l Mustang called him out and he kept right up. New Mustang is 430Hp? Not bad for a 6. He wants me to do the intake manifold as soon as I can. It looks all sealed with limited access. Always nice to have happy customers. Thanks, Charlie

Could you guys get an intake from salvage yard or maybe new if they are not really pricy (not sure??- ) and do the work-maybe split it or section it and epoxy back together, then swap? Might have more time to refine and test—
Looks nice Charlie!

I actually priced a new intake for just that job you described.
I would need to sell the job and extra cost which may not fly.

Was the MAF looked at before and after? And with what software. Curious how the fuel trims looked before and after.

You make a good point. I should have a good scanner but I don't. Put that on my list. I would think a modern design as long as you don't introduce way more air than it had stock would be able to compinsate.

I see there is a lower intake manifold as well. I have never split one of these plastic manifolds. I am not sure it is possible or worth the effort.

it appears that lower and upper are bolt together type, with seals around the ports. Looks like it would be easy to port the bottom part, match to the cylinder head, and port match where the upper and lower plastic parts join. Flush everything good with a pressure washer to remove debris
too lazy to make power w/o boost
