Cold air intake vs. cone filter on MAF...

[Turbo6Smackdown]

I would say no. Octane is the cure for detonation, not cooler air.

Cooler air will make more HP, but at the track, if you are running with a hot engine compartment, you aren't getting the most out of your T/R, anyway.

So much air flows into the engine compartment of a T/R that the difference in temps between in front of the firewall and behind the firewall at the track won't be enough to show up on the time slip.

But don't take my word for it, go to the track and run back to back test until you are sick and you won't see .1 second or .5 mph difference at the track between the best CAI/Ram Air and a K&N on the MAF.

Thank you. Had to bring this back up, as some people aren't believing me when I tell them, that when I ran my filter outside the engine bay, there was hardly any IAT differences on my scanmaster. Unless you have a 195 T stat in your car, and you're in arizona, then cai's are worthless.

What I can't understand is, by the time you feel the need to 'have' to run your filter outside the engine bay, for 1 freakin degree of cooler air, you probably already have either a really nice SLIC, alky, or both. So why in the HELL would you need one degree of cooler air, with a 250 dollar cai rig, when you already have alky? I'm lost why these new 'should I run my filter...' threads keep coming back up....

You ask why does the "Should I run my air filter" question keeps coming up?
There are alot of repeat subjects on here. Do you think everybody has been on here for over 2,000 posts and has seen every subject posted. There are new turbo car owners wanting questions answered, and some of us that are still learning which is what this web site is all about. The topic subject is posted up front - If you don't want to read about it "again" then skip it and go find a Brand New Subject that has never been discussed before.

I say that, because it's a subject, with an easily searchable history. I NEVER get on another member, for trying to learn. I just see this subject come up a lot, and people don't listen to me when I tell them the right answer....
And who are you anyways, to be tellin' me ****? Go piss up some other board members tree son, I got work to do.

Even though I've seen this subject before & went with a cold air kit, the more I read the more I second guess myself....

Yea. There's a few subjects that I thought I knew as well, 'till I continued to read here. That's why I spend quite a lot time doing nothing but reading. I always say, he who wins the most races, was most likely the guy that spent the longest in the books. You can throw 5 grand on a mustang in a weekend, and have it still pull off a 13 flat. I beat those guys every day, when racing.

When my car was running I saw a big difference in IAT going to a CAI vs the cone filter right off the MAF, but only at idle and slow cruise. When driving at freeway speeds it was only a 5-6 degree difference. I went CAI because I personally don't like that hot air blast just off idle when I accelerate from a light. Does it make a difference? Maybe not. My CAI is a second OEM MAF to Turbo hose connected to a 90 degre 3" mandrel bent pipe. I'm wondering if the guys with CAIs that have metal tubing are getting some heat soak at idle, thus counter acting some of the benefits of a CAI?

For those of you saying that you gained some good horsepower going to a CAI, did you also go from a 14" filter to a smaller one? Back in the day I had a couple friends who gained 2 tenths by swapping out their 14" to a 9". That was also just a cone filter right off the MAF.
