Guys,

I've done some searching on this but couldn't find a definitive answer to my question. I have an 05 6MT and looking to swap out my plenum and TB from an 04 sedan (polished). Are there any noticeable performance drawbacks?

Thanks in advance.

 

The uppers are the same...the lower plen. is different

 

^^That's right. You have a revup motor and I wouldn't run a non-revup plenum on your car.

 

Got it and thanks guys. I'd only be swapping the upper and the TB.

 

Why? This is almost exactly what a Motordyne MREV is...it's a modified non-rev-up lower plenum, and it makes impressive gains in a rev-up engine.

 

Not only that but, it's cheaper and the hp difference is minimal.

 

I believe non rev up paired with a motordyne space creates the mrev1 which will increase HP a little bit for rev up.

 

If you swap out the lower plenum, combine it with a spacer. If you have some tools you can to a little DIY plenum mods and really wake the car up.

 

That's exactly what I plan to do! Thanks for that! Non revup plenum with spacer combination on my '05. I might even file the first two runners down.
