this sh*t is incredible, what an awesome upgrade. Guys over at Kassel remote tuned for me, upped the redline to 7200, speed limiter removed, squeezed some more ponies out in addition to what im now getting with the stage 3 intake. Let me tell you, its very noticeably faster now. Very worth it if you're considering the mod. Can I say I have an si now?

Nice! It's not often you can get an honest 30HP boost out of a NA engine.

being I'm not the original owner of my Z. Is there a way to tell if this mod has already been done?

Isn’t it 40 hp between the 3.0i and the SI? Which if correct, is even better!

The posted upgrade in horsepower is for the N52 engine found in '06-'08 Z4's. You've listed in details that yours is an '03. That year has the M54 engine...not what this mod is about.

Thanks! Total cost for me was about $600... I got a good deal on a manifold with newer disas so I saved some money on those.

40 HP for $600 and no additional appreciate wear on the engine? NO BRAINER!

I did the same 2 years ago, the staff at Kassel are great. I recently added the sound tube from the intake to the cabin (baffles removed), sounds incredible. Got the complete setup off Ebay. The sound tube came with the factory Si's.
