Default Cold Air Intake Advantage?

I'm considering installing a cold air intake on my 1990 L98. I'm looking at a Vortex.
1. Is the added performance really worth the money?
2. How much of a pain in the a** is it to install?

Any opinions greatly appreciated!

I haven't seen anything besides a placebo effect.

Zip, zilch, nada, nothing.

Buy a factory air filter and call it good.

The stock intake system is a 'cold air' type.

I think the advantage is that you can do show and tell to people who don't know better and get adulation of those guys.

I was looking at the same mod - the responses from the pro's that have shared with you already sum up what I have researched as well.
It will look Kool - I also heard from pro's on this forum that "cutting the cowling" would also improve air flow - I'm searching for a picture from someone that has done this already.

Question is, even if you could improve the air flow, can you really use that extra air? This may be a case of "some is good, more must be better". Is your TB going to flow that air?

If you put a decal in the rear hatch window that says "Cold Air Intake" you may add an extra 10 or 12 HP.

Thanks for the info guys! Guess I will use that money for new weatherstripping. Sounds like a better investment!

There may be negligible gains for cold air kit, but cutting the air lid does reduce restriction and makes a difference.

You don't really think your butt is going to notice a few HP when the car is surging forward, do you? Are you THE PRINCESS?

Every 10 degree drop in air temperature is 1% in engine power. The cold air intake is a great way to get the most out of what you have in your engine. Monitor the air inlet temps on your car in stop and go driving in the summer and you will see 150 degrees plus. On the highway the difference is not so dramatic but it is worth doing in my opinion. I have the SLP intake and it works great.

Hello aklim - thanks for your input. I don't know if "more air" will help or not. I just got this 1990 C4 w an L98 motor in it for my son and I'm trying to do some "easy 1st mods" to improve performance. For me this motor is not real impressive as it is - good top end, but my wife's Cadillac SUV will blow my vette's doors off - and that just doesn't sit right with me!

Intake, headers and a chip tune will be a good start

Unless you want to dump money, you had better learn to live with it.

And just to clarify, that "intake" is not the air box, but the actual intake manifold.

Or trade it in for something more satisfying before you get upside down in the quest for more power. It can be done but it is easier with the newer systems.
