Air Filter

I was talking to my friend and he said he took off his air filter box on his car and now hes goin to get a K & N air filter for his. i was thinking about doing the same since i dont really have 200 for wizardair kit. cause i need money for my flowmasters. is it possible to take out the stock air box and just stick on a nice K & N cone air filter but still use the stock tubing that went from the throttle body to the box? couldnt i just match up the diameter and jsut get a clamp to clamp it on? thanks. if anyone has done it and has pics would be great! thanks ryan

You can do it but the only downfall is the stock tubing is a little restrictive and also you will have to make some hangers to stablize it from moving around.If you want somthing cheap just to start out with,I bought a whole kit from ebay,the tube and a cheap filter which I later upgraded for a K&N.I paid about 30 bucks with shipping.Just an Idea,but I would just wait until you get the cash flow and do it right.

yeah but the only thing is my parents are gay and wont let me use ebay. but i prob could get someone to do it for me.thanks for the idea. what do u mean by the stok tubing is a little restrictive?

WHAT!
All you need for an Fenderwell intake is
1. 7" or 9" cone filter -- I prefer www.Greenfilerusa.com
2. 2' - 3' section of Schedule 40 PVC pipe
3. a 60 degree bend for the PVC

The 2-3' section goes into stock F-duct....tighten clamp
60 degree bend goes on the other end of PVC pipe....filter then raps around bend...

you will have to unbolt some things in your fender but this is by far the best intake out there for the price!

FYI....Most aftermarket intakes use your factory f-duct

2-3 feet? damn thats pretty long ... homemade cold air .. yay!thanks for the idea .. i might do that. do u ahve any pics if u did it?

what year gp do u drive??

He drives a 99 according to his profile...

I always thought that the 99 airbox flowed good when gutted. Cheap and easy to do.

yes its a 99. um heres some pics of mine.

i see you made like a custom wall that the tube goes through. how did u make it? like what u use and stuff...and so does this angle piece go like right on the other side of the wall and how did u connect it to the straight piece? thanks sorry for so many questions. yall are great help!
ryan

i see you made like a custom wall that the tube goes through. how did u make it? like what u use and stuff

Plexi Glass wraped with Aluminium Tape then clear coated

...and so does this angle piece go like right on the other side of the wall

Yes the angle piece goes just on the other side


and how did u connect it to the straight piece? thanks sorry for so many questions. yall are great help!
ryan

You connect it with normal PVC glue....then the Filter and the F-Duct just clamp on with the hose clamps.

do i ahve to wrap in aluminum tape and clear coat it? and how is it stuck to the like chassis of the car? screws? ?

no you dont....and yes I screwed it in

ok 1 more question. thanks for dealign with me. i saw this http://www.pfyc.com/store/merchant.mv?Screen=PROD&Store_Code=PFYC&Product_Code=WB3032&Product_Count=2&Category_Code=GPUNDER and see they dont have that plexi window. so whats the difference if i dont put one in? so basically... do i have to have that plexi wall? or is it like a support to hold the intake?

Well from what I was told the more bends and angles in the intake tube the more restrictive it is,especially the F-duct because of all those ridges,the air tends to get caught up in there.The smoother and less bends from the air filter to the throttle body the better.Sometimes people get out of control and do all these turns and sharp corners trying to get the coldest air but are acually loosing horsepower and better off keeping the stock airbox.I removed the F-duct.On mine the intake tube is hooked up directly to the throttle body,from there a slight smooth angle to right above the headlight into a K&N filter.But everyone has there own preferences and designs.

The Plexi Glass that I have there is to stop heat from the engine to get to the filter.......my intake runs 5 degrees above ambient temps

what is the diameter of the piping i need to get taht fits in the f duct. like how wide. thanks,.

oh yeah thats kinda important isnt it!

What matters is how the car performs when the owners requires it. THere are few articles explaining the problems of using long tubing to route intake air but depending on where you live is what you can use. In a place that is dry and warm the fenderwell could be an option, but in a rainy location is another story.
Are there any sites with facts explaining the benefits of the 2' tubing compared to a CAI?

why is rain a problem....I live in Missouri and we get our fair share of rain and I have no problems with my FWI!

Here in PR on the rain season would be normal to have water from time to time up to half the door. My filter being inside the Thrasher CAI has goten splashes.

I'd be worried about the exhaust too....water halfway up the door would surely cover your exhaust.....
