Ok, here we go. Told ya'll I'd have a bunch of dumb questions. I am in the process of cleaning MAF sensor, throttle body, air filter element and anything else I shine up. Also installing plugs and plug wires. Anyway, I was reading an article about installing a K & N CAI and they mentioned how cutting a hole where it sits on the shroud will let more/better/colder air into the throttle body. Is this a common thing? Am I missing something? The article said the K & N setup wouldn't fit without doing this. Mine fits fine. But I can see how this would make a difference in the quality of air coming into engine. I just am hesitant to start cutting on the shroud. But I will if this will help me outrun a freakin GT mustang in my neighborhood.
Thanks in advance for hhelp.

Personally I wouldn't cut it. GM engineers knew how much air it needed and allowed for it. Will cutting the shroud get you a littler more and cooler air, yep. Will it help, IMO I don't think so. Without major engine modifications any horsepower changes wouldn't be felt it they were in fact recordable. Just my 2 cents

That's exactly what I was thinking. But I wanted to make sure it wasn't something everybody did and I was just behind. Lol
Thanks for reply.

I agree with Torch. In fact I had an older Hall intake that basically used the K&N filter. The car was in a good state of tune. I started developing hesitation after quite awhile. I consulted a friend who consulted one of ‘the guys’ at GM and he told me to put the stock unit back. I did and no hesitation. I trust the GM engineers who know a lot more about these cars than I do.

corvettte stuff, but man it's fun. My question is, when I change my plugs and plug wires, should I re
One other caution, oilEd air filters may foul the MAF.
Like Torch also agreed with, Yes, they will. I found out the hard way. 💰

My $0.02:
To me, the risk of destroying a MAF, is not worth the handful of ponies that might be gained by using an oiled air filter. Instead, I just replace it with a OEM filter as needed.
