Send DaveO a PM and get him to tell you what he has found to work the best in terms of temperatures.

And then tell him to PM me what he writes you cause I can't remember.

 

Ok Guys Don't Throw The Stones Yet! Aem CIA

 

you may see a slight mpg increase... no really noticeable hp gains with an intake and if you just like the looks and want crazy sound... injen FTMFW

 

Thanks for everyone's input. I think I'll head for the injen CAI since a few people said they have it and like the sound. I'd rather have a nice looking tube under my hood than a piece of black plastic like the ztube. Anyone know where the cheapest place would be to get an injen? I've found them on www.injenairintakes.com for $269

 

look in the marketplace..

keep in mind that you may have to worry about driving in water with the intakes that have the filter down below outside the engine bay. It's not a problem for most though. The long tube also makes it more difficult for the engine to draw air, but not enough for you to notice a difference.

 

anyone know where to get an injen air filter wrap cheaper than $37? If it does rain, and the CAI is not short ram, will it hurt the engine/not start?

 

I'd challenge the comment that the long tube makes it more difficult for the engine to draw air, simply by the fact that changing out the stock intake with its mass heapings of plastic ducts and airways to a Z-Tube or a CAI is far better than doing nothing. So taking out a majority of those oem plastic tubes helps off the bat.

Also, lets not get into the science of the density of molecules in the air based on temperature. So denser packed colder air picked up by a CAI will be harder for the engine to suck up than hot expanded air in the engine bay with a short ram? Then why does Stillen have such a detailed heat shield on their short ram?

Being a CAI user myself (AEM), I have found to have excellent performance gains (whether butt-dyno or actual) and an awesome sound coming from under the hood. I acknowledge the potential of sucking up water, but heck...I live in LA (We're in the dryest year to date) and even with my car lowered, why would I ever be in that deep of water, whether just driving through a puddle or something else. Basically, if you live in a warm weather climate, why wouldn't you go for a CAI?

 

what does sucking up water do? does it ruin the engine or just not start? and how hard is it to switch from the CAI to SRI.. and aren't both included in the injen CAI system?

 

Does aem still offer its cold air water bypass system i had this on an rsx-s and it worked great....

 

The theory is that if you drive thru deep water, then water will get sucked into your engine and cause serious damage (water doesn't compress when the piston rises toward TDC like air does - so the rod bends, the head gasket gives out, etc). I think that the water would have to pretty damn deep to actually make this happen. AEM (and probably others) sell a bypass valve which opens to allow underhood air to enter if the filter is totally submerged. Everyone talks about the dreaded hydrolock, but I don't know anyone whose actually seen this happen. Maybe its an urban myth?

 

well maybe I'll look into one of those bypass valve.. I live in CA but when it rains.. it usually rains hard, and there are a few places where i've found myself almost hydroplaning through a puddle... Once, I thought my bumper was going to blow off because there was a huge puddle at night that blended in with the road and I was going a good 30-35mph and I hit it and felt the car sort of lunge downwards

 

he'll tell you that if you stuff a filter down the bumper you are sucking in air that avgs 20 degrees hotter (from residual heat off the asphalt)... also the long ram has a negative effect on performance as proven from dynos... and for those "prove it" people I've seen boatloads of dyno charts and Tony (MotorDyne) has tested this as well...

Sorry, not tying to speak for Dave, but he doesn't post out here anymore - which is a shame because he is a wealth of knowledge and has TONS of documented research!

 

there are reports of it happening on the various boards... in fact I think on my350Z it happened to someone recently... you can check the intake exhaust threads there and read about it...
