would drilling some holes in he intake airbox help bring in more ambient cool air? any downside??

Thankis

 

Yes you can, and yes it will. The downside is, you are hacking up a factory component when there are plenty of after market CAI's specifically made for this purpose.

 

But the upside is you will have achieved the same thing as most of the aftermarket air filters setups and not wasted any money

A little tip, if you do cut the holes cover the holes with some kind of screen to keep out some of the junk.

I've got a Blackwing on my car. It looks good, has a washable filter but it wont perform any better than a stock airbox with holes cut in it. Add a washable filter (like the k&n or the Cool blue, or some of the others and you have achieved the same airflow as some of the $300 - $400 aftermarket filters.

But it doesn't look as cool

 

The only question I would raise is, how do you know that the opening in the stock filter housing does not already flow as much as the throttle body can take anyway?

Drilling holes could just be adding more holes with no benefit.
I still give the GM engineers a little credit for designing a system that is not going to be unduely restricted.

Same with the stock air filter. There is a trade off to make them less restrictive. The less restrictive the filter, the more dirt gets into your engine. Plus, some studies have shown that aftermarket filters may start out less restrictive, but they get dirty quicker, pass more dirt, and eventually become more restrictive. When paper filters get dirty, you just throw them away, and do not have to mess with cleaning them. A lot to be said for staying with the stock paper air filter.

One other note... some people do not like Fram oil filters, but I like the air filters. I just bought a Fram air filter for my Impala, and it was identical to the ACDelco filter that came on the car. I compared the Fram filter to a WIX air filter (since I like WIX oil filters), and it also looked like they were made by the same manufacturer, right down to the color of the orange rubber trim.
One other odd thing was that the WIX filter for the Impala cost $22, while the Fram filter for the Impala and the Z06 were both $12. crazy!

Vararam!!!

 

Many thanks to all you senior members for offering some very helpful suggestions to my question. I knew you guys had probably been there, done that!! Thanks for sharing.

 

How hard would it be to put a F.A.S.T 92 MM lsx throttle body and intake on a 2000 c5 ls1? And how would u do it?

 

If you really want to know, why don't you start your own thread instead of hyjacking someone else's.

 

Come on LJ, new member, 1st post, got to give him a break.

 

That's one of the problems with messaging as apposed to actually conversing with someone face to face (intent can become misconstrued) perhaps I should have ended with a smiley face. I didn't mean to sound like I was coming down on the guy for breaking the rules. I was telling him if he really wanted to know the answer, rather than hyjacking someone elses thread, he should start his own.
