well according to jbrady and some other guys that made their own airbox, I have finally got a spare from the junk and tried it on my own. I havent drived with it yet so i dont know about the power gain... But i did pop it in real quick and it's some what louder than stock... sorta sounds like a muscle car

but here are some picture for those that want to try it:
The plastic is so freaking hard that i needed to drill holes all around then cut through them with my picket knife saw.. hehe

 

number 2

i'm running a Bosch filter and that diameter should be around 8.5-9 inches

 

Do you have the name and address of the junkyard you went to?

 

yea I got it from All Toyota Lexus in San Diego California... I'm not sure if they still have more, its something you need to keep calling for. Good luck trying to find it if you've never been to Otay Mesa

Thanks for the info. SD's too far so I'll probably have them mail it if I get anything from them.

 

sounds good, I want to know what Jbrady thinks of the airbox? I dont know if I did it too large compared to JTTLS400's

 

persian, I have been out of town and just got your PM, I will respond here.

Yes, the plastic is VERY hard. I used a sawzall blade in a handle and sawed on mine for about 20 minutes. An air cutoff tool should be much quicker.

I am glad you made the hole larger than JTJerry did. Mine is actually larger with no curved area on the top left at all, just 2+ inches all around the edge of the air filter and of course keeping the snorkel inlet part of the housing intact as you did. Yours should be fine. Now, you need to create a heat shield to block off any air flow from the engine compartment. The larger the area the filter can draw air from the better but it must not be hot underhood air. JTJerry removed a couple of plugs in this area, one over the headlight wiring and the other next to the fender. I would recommend you do this. He also said he was able to draw air from around the side of the radiator area but I could not make out how he did so from the pictures he posted. The goal is to find as much cold air to feed the air box heat shield area as possible.

Did you drive it yet?

At present I have my mufflers back on and last night comming back from the store I went under a long bridge with the windows open and the car in first gear... full throttle... sounded REAL STRONG!!! Louder than it sounds from inside the car... a A LOT LOUDER!!!

 

thanks for the response jbrady, yea I removed the light covers that JTJerry did, I'm just about to start on a heat shield and find the right material, I'm guessing I should hit a Home Depot or sometin.. I got some what of an idea by looking at yours.. I'll keep you posted
