I've been planning on buying the gmpp intake, but I am trying to save up to buy a house, so spending extra money isn't really something i'm wanting to do. So I decided to find an alternative. I, like most everyone else, was looking for performance gains and increased fuel economy.

So I went to autozone and picked up some flexible hose, and a small breather. I ran the hose from the throttle body to the air box, using the rubber pieces to help everything seal up better. the breather then went on the hole in the valve cover.

It actually made a noticeable difference in performance, above 3,000 it seems to pull a little harder. the sound is very much the same as before, at idle there is no difference, up to 3,000 the sound is SLIGHTLY louder, above 3,000 it is noticeable, but far from loud or annoying. on the highway there is no difference.

on a scale of 1-10 I would say it was about a .5 on the difficulty level, took me about 3 minutes to put on. the best part is what the spendometer saw, only $37.99 with tax.



I have the lower intake part before the filter removed and a gmpp touring exhaust. for those who want to know. the sound is very tame, not enough for anyone outside the car to give you a 2nd look, but enough that you know what the engine is doing.

 

hmm take that off, its hurting your performance with all those ripples in the hose.

 

yea the ripples make the air run apart, causing less condensed air, which in turn causes less of a gain in hp cuz the more dense the air =the more gain

 

^^Yeah, the turbulence is not helping at all.

 

return it, and get a round shaped hose, it'll help more

 

in that case get a turbonator on ebay for cheap. 20WHP !!!!

 

that's not helping any, guaranteed. i got this from pep boys for 40 dollars, same price, and it's smooth, and actually looks good.


.

 

agreed! looks a lot better. And you can still paint it black if you want.

 

I go to an auto diesel school and they dynoed a car before and after with one of those tubonators and it LOST 12hp to the wheels with it installed.

 

that pepboys one looks pretty good.

sure the turbulence could hurt performance, but look at what happens with the stock thing. look what happens after the throttle body. lots of turbulence there.

I know its not very scientific, but the butt dyno is telling me its working pretty well. i'm even seeing an increase in fuel economy (back and forth to work, same speed, same everything) according to the dic.

eventually I will spring for a gmpp intake, but for the time being this isn't bad for the money.

 

That is pointless.

 

where did the rumor get started that the OEM intake system was bad?

after market ones do sound cooler, sure, but i don't think my car is any faster with one.

 

This is going to get ugly...lol

 

no, please keep your pants on

 

No no...not that type of ugly.

 

the stock intake is not 'bad' but compared to an aftermarket intake its not as good. the huge airbox that sits on the trottle body stock is definatly leaching a few horses. pretty much the worst part of the stock design.

 

ok, whew

 

just do airbox mod. cheaper and better.

 

so, do you want a cookie?

 

It's a good buy if u can put it together without it breaking. Im just going to get a intake boot and have a muffler shop bend a pipe for me. Will give updates on how it goes friday.

 

Please take that off. It's horrible for your car.

 

what do you mean without it breaking? i don't think there was ever a concern about it breaking.

 

And ugly!

 

who remembers the washing machine hose held on by duct tape, and the guy was saying how he invented this great new mod?

this is bad, but not as bad as the other guy.

 

the pep boy's spetcher or whatever it is should work... i think auto zone even sells a gm maf port to put in the sensor. then you can get a cone filter and have some alright gains.. and maybe not though a cel..
