PVC pipe can melt at underhood temperatures and release toxic fumes into your car, thats all i have to say about that lol

PVC melts at 100-260 celsius. I don't know of a moving car to get that hot under the hood.

PVC does not out gas until it'* over 180*, closer to about 195* Doesn't reach a plastic state till around 250*. If your engine bay is getting that hot you have other things to worry about.

I'm highly doubting that...just got back from a 40 minute drive.. both highway, beating on it, stop and go, and sitting in a parking lot idling for 15 minutes to test everything out.

After idling all that time the pipe itself was cool to the touch believe it or not.. I have felt PVC warmer than that just from hot water from a Hot tub or pool down here comming from solar panels.

Agreed.. like I mentioned above.. it is not going to get that hot under there. Having worked in a shop changing oil on cars in the summer time back when I was younger..when cars were really hot I would say it was 130-140 degrees under the hood..now obviously coolant lines, exhaust manifolds etc.. are much hotter lol, but the temp under the hood, nah..nothin to worry about with these intakes

Oh and an update after driving around for a while.

I am in love with this car all over again! Say what you will, but this, or any FWI for that matter, definately makes a difference!

Throttle response is much much better, just snappier is how I would describe it.

The engine feels like it breathes better now.. I got onto the interstate..I mean a closed, monitored race course.. doing a 30mph-95mph run..and it just seemed to pull so much better at 3500+rpm. I can only imagine what it would be like on a Supercharged motor.

The results have me pleased enough to say that even if I paid the $170+ from some supplier out there for this I would be happy with it.

There was some past members that insisted that PVC would destroy your car due to out gassing. These claims were made with no proof. I drove around with a temp probe in my engine bay for several weeks and watched the temp close. Even on a hot day I only saw about 145* when not moving. As soon as I started moving that temp dropped. You can also scan your IAT and that will also tell you what temp it'* being subjected to.

People will believe, and stick to what they think..nothing you can do, but a little research will prove to them everything you are saying. PVC is safe to get up to hotter temps than under our hood, and that is hotter temps UNDER pressure from water...no water or pressure here, so It is perfectly safe/fine to use.

There is a difference between PVC and CPVC that would have me lean towards making the KAI out of CPVC.

CPVC can withstands higher temperatures and its is chemical resistant. With PVC, I would be concerned about it'* ability over time to withstand oil, gas and or cleaning agent you might use in the engine bay.

It does look sweet though and a nice job!!

Hey Guys!!!

I just received this exact Cold Air Intake from younggun, and as an honest opinion, this is a GREAT setup. The instructions were very well written and easy to follow, with detailed pictures of EVERY step, and also includes everything needed to complete the installation.

It took me about 40 minutes to install, and that included me cleaning thorougly the area under the air cleaner box since its never been cleaned. After installing the CAI, I have noticed a significant change in the throttle response of the car. The throttle kinda seemed to lag (SLE model, could be the reason, may not be an issue with the SSEi'*) and this was taken care of with the CAI. After installing the CAI, and driving 50 miles back to school, mixed country and highway driving, very little city driving, with a pretty steady wind, i averaged 33.1 MPG which I'm sure is a little lower then what i would have gotten with warmer weather and less wind!

So all in all, im very pleased with the performance of it, and it looks GREAT after being painted the color of my vehicle. I will try to get pictures up within the next day or so!

Thanks again to younggun and his good work!

Eric
