Well the stock plastic crap came out of my car finally yesterday! It only took 3 years. here it is, basically the same as what Larry Ganz has on his websight I think. Just a PRM, a Kartboy MAF adapter, a 45 degree bend and some silicone tubing. So far I love it, and I have not seen any lean conditions on the A/F guage.

My initial Idea was to use a modified Minnam intake tube and a PRM to make a MY99 Cobb-like intake. I got the PRM and the 45 deg. tube from Larry along with one piece of 3" blue silicone hose and the silicone hose to line the fender hole with. I later decided to go with the stock air box, so I sold the Minnam. I needed a 2.5"-3" neck down silicone hose which I got from my friendly niegborhood Honda tuner and some hose clamps amd 6mm (1.0 pitch thread) nuts from the hardware store. The MAF adapter was from Kartboy.com. I still need a short 3" tube to put in the inlet of the PRM so it will stay put in the hole. One thing, because the MAF is so far back, I had to snip a wire in the harness and splice and solder in an extension to get the harness to reach. You can see the darker black electrical tape I added today. So far, so good.

Uhhh... I remember 8dude, I mean 8complex saying that If your planning on moving the MAF, the MAF had to be the same distance, from the TB, that it was originally to work correctly.

Give me an excellent technical explanation as to why and I might agree with you. The truth is you can put it where you want. All the MAF does is tell the ECU what the air flow coming in to the intake manifold is. When I first started the car after the ECU reset, it ran weird for about 2 minutes. When it learned the new setup it ran fine and has so ever since. No problems. Just added horsepower. The only problem I can see with moving the MAF back, is possible increases in exposer from pulses from the throttle body. I think the stock airbox will absorbe most of that, so I am not worried.

God, I hope you don't think 8Complex knows everything! Nobody does! Not even me.

No really, I don't!

Yes, but I have the new, improved recall MAF! Just got it about two weeks ago.

Why do you think I had a stock intake system including the snorkus for three years?!

(BTW Recall MAF's are covered for LIFE!!!!)

O.K. to settle this once and for all... you can put the MAF anywhere you want, as long as there are no air leaks between it and the engine, ie you can put it in the trunk if you so desire, and run the tube through the middle of the passenger seat back, and as long as there are no air leaks, it will work just fine.

The MAF doesn't care one bit about air pulses or location.
Air flow is determined by the ECU based on the frequency of the MAF output,(which is the frequency that the transistor inside the MAF operates at to keep the hot film at a constant temerature, so more airflow, the transistor switches faster to provide more current) Intake air temp (measured inside the MAF sensor) and Baro pressure (that sensor to the left of the MAF in the picture).

Yama... you always gotta bring out the credentials. GM needs all the technical assistance it can get... espically with you on the phones! HA!

Anyhow, nice intake setup Fred... I'll have to check it out if I EVER get back to Shores. School sucks.

Don't worry, you'll have some credentials one day...

Didn't you mean they need all the help they can get especially with you in the dealer?
