Thread: cai or ram air for the GXP

Very well said bio, I was simply trying to save this guy money he could use elsewhere. Would my setup be better in a box, maybe, it's all a big debate. I caught a lot of hell on my new setup on a few other GP forums. One guy even went as far as saying he guarantees that my stock airbox performs better than what I have now. There's no way in HELL the stock air box out performs what I've got, no way. I can fell the difference, when you feel the difference you've gained more than just a couple horsepower. I'd say 15hp easy!

I'd hope so with a 5.3 liter v8

1. I work 10-12 hour a day 5 days a week, have 2 kids and just don't have time to design my own intake.

2. I make enough money that while I don't like spending $300, I can afford it if I save money for a couple of paychecks.

3. If you make it yourself, you do not get the help from K&N's lawyers if your dealer states that your intake destroyed the MAF, Cat, cam, piston's, etc. K&N's intake even has a handy 1-800 number to call if the stealership gives you hassle. I have actually used this service when a VW tech said that my K&N intake cause my cam to fail in my turbo VW, the lawyers talked to the tech and voila...warranty work with no more hassle.

4. The shield, while not blocking all heat, appears to do a fairly good job as after an hour of driving I can touch the clamp on the filter and it doesn't burn me, where as the clamp on the MAF housing does burn the hand...not one of my smarter moments.

5. Since there is very little support for the GXP, I have to believe that the R&D that K&N does is a little better than Joe fixit who uses PVC tubing and roof flashing to make an intake. Not banging on those that do it, more power to ya, but I am not an engineer, so I will leave the engineering to the people who know what they are doing. Just a change in materials, I think, can change the flow characteristics of the intake...but once again I am not an engineer, so that is just a guess.

well said man, i'm in the same spot right now wit my family/money. and i don't need no v6's (who cant get "fast" unless they the put a bunch of stuff in their cars). i know guys that have GT and GTP and i dont see or hear half of the BS as i do from this forum from some tuned cars talkin about stock cars, (who mind you) would destroy you V6s if we had a market to tune our V8.

in the next 2 months i will be getting the K&N, i was trying to find somebody who has put one and has pic of how they did it, but to no avail.

You need some pics of the install or of it on the car? I didn't take pictures of the install because it was so easy following the directions...I think it took me an hour or so, but I was drinking beer and bs'ing the whole time, so it probably took longer than it should have. If you want I can post a picture of the finished setup for you.

lol sounds like fun to me, sure post them pics up man that would be great.

I'll get the pics up this weekend, the directions are very easy to follow and if you lived near Roswell, NM I would help you install it...

it took me probly a half hour to take my old out make one and put it in

oh gosh hear we go again. see i know that the intake is restrictive that y i want to change it.

oh my bad lol. i would love to put in a LS6 manifold in there but its mad expensive , not only for the part itself but for the parts it needs to be put in there .

i would daff pay somebody to do it for me tho.

Sorry I didn't take any pictures this weekend...I was stomach flu'ing it all weekend and vomiting took up pretty much all of my time. If it is still light out tonight when i get home I'll get the wife's nice camera out and upload the pic tonight.
