I had bad luck removing my screen with my modded stock airbox, and I think it was because my flow wasn't laminar enough. I haven't pulled it yet, 'cuz I want time to drive it and make sure it'* ok without having to worry about something coming up and driving a dogshit car somewhere. This weekend, it'll come out and we'll see how she does!

I'm pretty certain with the intake'* ability to provide laminar flow, even if it is rough at first, that it will 'learn' very quickly this time. I think it'* worth the little bit of extra flow if the ADTR negates the need for the screen anyway.

Everything sounds great..i'm gonna have to buy an intake here when i get some more money. Either that or exhaust will be one of my starters for engine mods once i get some more money accumulated.

Hey will, I've noticed something...your engine compartment is taking on a red color scheme. I wonder why that is. Maybe because RED ROCKS!

My engine bay has the same color scheme.

They don't make green plug wires, filters, or wire housing, so we had to settle for 2nd best. ... right Will?

What would the gains be like on a Series 1 N/A car? Would there be any loss of torque?

HP and torque gain. Maybe not as much as with a SC, but Hector'* car was actually the first test car, and he said it was phenomenal. If you can notice the difference from simply installing a replacement k&n, you'll definitely feel this beast. Very snappy on the throttle response, mostly low-end, but even easily noticeable on the freeway. Lilpooky and I smoked a couple cars in a race to the offramp this morning. Definite improvement!

Ok, here'* what I know so far:

My MAF screen removal with the modified stock airbox was BAD. It wouldn't idle. With the ADTR intake it was no problem. Not even a hiccup, and I can feel the difference. The laminar airflow theory proves itself again.

The Series 1 upper plastic intake on the NA cars is also angled forward like the Series 2. Should be a beautiful fit.

Both the Series 1 and Series 2 SC cars are STRAIGHT TB'*. This not only affects the angle of the the intake, but also how far it reaches into the 'pocket' behind the headlight. Mine comes close, but it really tucks in there on Jseabert'* car.

IAT lengths on the Series 1 NA and SC are already good for putting the sensor closer to the filter. No need for an extension harness like the Series 2 needs. Series 1 is a larger sensor body than Series 2.

The only other issue would be the different diameters of TB'* through the years. 3 sizes total. I think Hector already has all that figured out.

What this all boils down to is that it appears only the SC models will require trimming an angle on the silicon adapter, or a different bend in the pipe. All Series 1 IAT'* should be positioned near the filter. This difference between Series 1 and 2 could be solved by providing a 5/8" grommet near the TB for Series 2 AND a 3/4" grommet near the filter for the Series 1, and a 5/8" and 3/4" knockout seal or plug for the unused hole. It would be a universal inake that way. That'* exactly what I did. I left the original grommet in the intake, and found a small plug that fit inside it. I also used clear rtv to make sure it sealed and held.

The performance improvement is amazing. So is the wonderful whine of boost. Not overbearing, but noticeable to the untrained ear now.

Looks pretty warm in there Will.

Can you relocate that huge water bottle?

After a run, shoot the temperature of the filter and pipe. I'll bet it'll be around 130 F !

I'll be interested to know if your acceleration times have actually improved.

Looks great Will ! Can't wait to see some in stock at ADTR.com.

I assume that this kit is (beware, geek alert): plug-and-play? As in, I don't need to do anything else to get it to work as intended (new PCM, flash the PCM, etc.) ?

I DO know that I'll need the extension harness since I'm a series 2 (2000 SE). But I also notice that some other hose is coming out of the airbox (besides the one going to the TB). Clearly I don't know my way around the engine bay too well, so I'm not sure what this is.

Any info you can give (regarding the plug-n-play and the airbox hoses) would be great, guys. Thanks!
