what do spacers do for your car?

 

are you talking a plenum spacer or wheel spacers?

 

yea, please be a little more specific

 

Intake plenum spacers = more volume/increased airflow. In the case of the skunk 2, some additional thermal isolation from upper to lower plenum. But skunk hardware that comes with the kit is junk. Too bad since the spacer itself is actually pretty nice. Stick with MD iso for a reliable install to get a larger, cooler intake charge for more power.

Wheel spacers = try not to go there. Best to get the right wheel offset to begin with.

 

or speaker spacers.... ????

 

Given, you posted your question here, ballisticus has given you a good reply with regard to a plenum spacer. MotorDyne is always an excellent option.

 

the plenum spacer make more room for the air to flow. Wheel spacers comes in various sizes to move out the rims/wheels outword.

 

obviously if he posted it in the exhaust intake forum he is talking about plenum spacers.........they allow more air to flow.......more power

 

which is better, ½ Crawford Plenum or Motordyne Engineering 1/2" Iso Thermal plenum spacer

 

what year is your car?

 

2006 g35 coupe 5A/T

 

The MD 1/2 spacer is a good option!

 

wat about for 03 5AT?

 

You guys are too nice. My word of advice is... SEARCH!!! There are eleventy billion threads about spacers. This has been all covered before... well... eleventy billion times!!

 

From the many threads that Ive read, go with the 5/16. If you dont care about your engine cover, then the 1/2.

I remember reading a thread where the 5/16 gave a better gain through out the majority of the RPM range.
