Does anyone make a CAI besides K&N? Does anyone make lowering springs, F&R sway bars, lower temp thermostat?

Dang, those are hideous.



Now, this one is nice but only made for the 3.8 SC. I emailed the company to see if they could make one for the LS4. I'll post when i get a reply.

That does look nice and functional. I would love to see one for the LS4 be pretty close in design.

I got a response back:
We are currently working on an 04+ GTP intake, which is in the final testing phases.

We would love to work on and build a unit for the 5.3L engine, but would require a test vehicle for a couple of fittings and eventually a dyno run. Our testing and prototyping is done in Milwaukee, Wi so if there is anyone in the area that would be willing to help, we would be more than happy to get the ball rolling on this project.

Please feel free to email or call if you have any questions or concerns, and I will make sure to keep your email and give you a heads-up when the unit for the 5.3L becomes available or soon will be.
I don't think they're a sponsor here, so send me a PM if you are interested in prototyping and i'll send you the contact info!

Here are some more pics!

Can't speak for the other W-bodys. But if you take off the driver side tire and splash guard on the GXP. You can run a tube like I did from under neath the fog light there is a 4 inch wide gap about and bring it right up to the rectangle hole down by the CPU.

Wonder if that's big enough for our motors? My 04 Lancer had a 6 inch cone and it was one of those 102hp engines 2.0l
