Surprising on the 74mm comment. I appreciated the difference with it. Not night and day but definitely a noticeable difference. Has anyone noticed a posted "performance gain" number on Needswings site? I don't recall seeing anything there.

 

My recall was it is about a 15 hp gain projection. I can't remember exactly where I saw it but I'll see if I can find it and post it.

I found out where I got my numbers from. It was from an email with Rob at Needswings when I was inquiring about the HP gain potential. Here was his response.

"Hello, we haven’t dynod the cai’s on the na’s since we made improvements on them but for a estimate I would expect to see 10-15 on the cai and ~ 20 on the dcai. We have lots of flow bench data just not dyno data sorry. "
Thanks, Rob

Given the work they've done on this system, I expect the air flow data to be consistent with their estimates.

 

It's hard to imagine that a few guys in a shop that like HP can out engineer the guys at MB. The car does come stock with Cold air system and it's obvious that the NW single and double together with the TB upgrade are making provisions for more air. Typically, Forced Induction engines are easily boosted and are restricted by either air or fuel. On NA engines, cold air tends to help create horsepower easily because there is no SC or Turbo heating the air on it's way to the manifold. This is where the inter-cooler comes in! The NA cars have no additional cooler so engineers search for ways to get the coldest air to the manifold possible. I believe that NW has found the most cost effective way to bring the coldest air to the N/A cars while also allowing for more air as well to the SC cars. Every NW intake looks like jewelry under the hood making the intake both system functional, and aesthetically pleasing.

A large number of intake kits actually hinder performance on cars so we are lucky we have a company that provides intakes that do not rob our cars of performance.
