Hot CAI Pipe?

[johnnyd6404]

I have noticed that my intake pipes are noticably hot. Is there any good insulating wraps or somthing to keep the two pipes cool, or does the pipe being hot not effect the performance. I have noticed some power loss after driving for a long time, but it could just be in my head. Any input or products would be great.Thanks

what is a cold air intake

[DevonD]

Yeah after you have been driving a while your car will be slower.. If its a TRUE Cai that shouldnt really be a problem. But if its just on of the cone filters that sits lower down in the engine compartment its not Cai. When the engine heats up its going to be pumping out tons of heat and that air intake will just be sucking it in making your car slower..

Also you say two pipes..what do you mean by that? Do you actually have dual intakes? Or you are just talking about the two sections of pipe in the intake system?

go to an hvac supply store and get some insulation - 4-6" wide and wrap it arund the aluminum pipe - the higher the R value the better the insulator, just make sure it can stand up to engine compartment temps.

I have the injen cai which comes in two sections but it does sit lower in the engin conpartment behind the radiator not in the fender well but isn't that still a cai?

[allensteiner]

nope...it sucks hot air straight from the hot radiator. that's a wai - warm air intake fenderwell intake is a fwi and it's not really a cai either. if you run your pipes into the bumper and insulate them from heat so you get colder iar in - that's a cai. don't worry though, unless you have a turbo and the air goes thrugh an intercooler it's always going to be warm. there was a write up here somewhere where a guy cut out parts of his stock intake box to make a heatshield and wrote that his intake air temp dropped from 100+F to 60-someF - look around for it.

injen FTMFL!

even if you do get a "real" cai, heat wrapping it is not going to matter much. its not like your FI. why spend money on heat wraps on something that will show minimal gains.

your best to just keep the stock intake as its designed and engineered better than all of those crappy cai's. the snorkel provides cooler air from outside the engine bay, which is why it helps. it has been proven to increase vacuum in the engine under heavier throttle conditions as tested by one of the maxima.org members. plus, its made out of plastic composites which deflects heat better your cai.

go back to stock

i'm still skeptical about that. i actually want to see those logs.

so if that "stock heat shield" actually helped, imagine what a normal fully closed airbox would do. thats why, i suggest just keeping the stock intakeand actually do other mods beside air intake oriented that will reduce temp and heat soke. couple examples, t-stat mod, and plenum spacers.

I partialy agree with you the plastic stays cooler but it deffinatily does not preform better. I have much better response and power not to mention the sick sound it has so stock is restrictive as far as I am concerned.

yea your right about sucking hot radiator air but i dont think that set up will work were mine is sits vertical I saw that injen makes a heat deflector but its polished aluminum so that wont help much. Oh well it still sounds nice just was hoping to squeeze some more out of it. I will say that I did get about 5 percent increase in mpg city and almost 20% highway so it was worth it for me. Plus who doesnt like that growl

[DevonD]

Yeah I agree. You MIGHT be getting cooler air with the stock box but its so restrictive it ruins it.. with the cone filter or WAI settup your getting way more air but its also warm air.. I think the WAI has a slight advantage over the stock box.

[allensteiner]

best way to go about getting cool air in is to cut a hole in the hood, slap a scoop on it and route a closed box air passahe to the intake - cowel induction. a company called spectre makes a bunch of adapters, hoses, filters and elbows witch might make it more possible. i was thinking about doing that OR...get a short intake with an open cone filter, attach a flexible hose to the open part of the filter on one end and run the other under the cowels - the plastic grille between the hood and windshield - supposed to be a high pressure area and no bugs or water...unless it's raining but if the opening isn't pointed upwards it shouldn't catch too much water.

def does not perform better? are you serious? YOU THINK you have better response and you THINK your butt dyno tells you have more power all prob because of the name brand that you paid $$$$ for and that stupid it makes. its been debated and proven before and injen is one of the worst CAI you can get. CAI's are just commonly known as noise makers. sorry buddy

how is it so restrictive?

you can also just simply remove the air resonator that sits inline with the snorkel. all that basically does is resonates the intake noise and maybe possibly reduce some restriction but as far as i know, the stock intake performs just fine.

[DevonD]

well i mean think about it.. its sucking air in from a maybe 1 inch tall slat thats jammed up against the hood, and it does work just fine. Im just saying having a gigantic cone filter is better than a slat under the hood. And if im wrong please explain Dyno results to me becasue they point to the same conclusion. They might not be huge gains but its somethin at least.

And if you were to remove that resonator box you would be oppening up the intake pipe to that warm air behind the radiator through the L shaped pipe on the bottom side.. so doing the same thing as a WAI...

the snorkel is designed like that to actually "ram" air into the airbox.and there have been reports that the stock resonator/accordion tube helps low end throttle response, as well as the snorkel.

however, you can still remove the resonator and just place a block off plate or simply put duck tape over the hole so warm air won't enter.

i know there dynos out there and i know the short ram intake actually shows some gains as well. but i don't feel like searching at the time...

Damn whats up with this chick I'm not tryin to debate the performance of it I was just looking for something to keep the pipe cooler. Chill out you dont need to be so nasty, sh** everyone has their opinions but damn

i'm not a chick. and i was trying to make a point and save you some money but whatever, do what you want.
