Does anyone feel the difference after installing one? In other words, is it worth the price?

 

Can anybody really feel a 5-10 hp gain out of 300 hp? That's only a 2-3% difference.

You're never going to feel such a small gain but it would certainly be measurable on a dyno or in a 1/4 mile ET. For that reason, yes, it's worth the price.

 

My wallet is lighter = faster car

Seriously though.. there are quite a few posts on spacers and other plenum mods. Start at www.motordyneengineering.com .

 

Your could search this.................actually you should search this.

I feel the need for speed.

 

Roll "Danger Zone" from Top Gun soundtrack!

 

I recently had a Crawford upper plenum installed along with a JWT Popcharger and GReddy Evo2 catback. I had it all installed at the same time but i didn't reset the ECU, i just drove the **** out of it for the next 300 or so miles. So 2 weeks later... i honestly don't feel that much of a difference on the butt-dyno but i did notice that it pulls thru the upper RPM's (5k+ rpm) alot faster.

Cliffs notes: not much on the butt-dyno but pulls smoother thru the upper powerband. Not sure if that makes sense but thats my take on it.

 

yah... md spacer is a lil cheaper...stealthier...as good a gains as you will get with any other n/a mod otehr than test pipes.....exhaust, like hks you gain..8-12 whp... at 1400$...yah right def the hottest looking exhaust

 

What about gas mileage? Any Change?

 

i didn't notice a change with gas mileage. the same ~18mpg of city driving as before my crawford plenum. if anything i drove the car harder.

 

+1 with the Z gas milage is relative to your driving habits
