whats the best plenum spacer to get and is it worth it?

 

I believe the Skunk2 spacer is a good 1, as far as i know it produces 10-12 hp

 

MD 5/16(better mid gains), MD 1/2(better topend) or Powerlab 3/8(somewhere in the middle and the cheapest).

 

what about the z1 motorsports spacer...anyone hear anything good about that one?

 

Sounds cheap. Go with MD their products are dyno proven and they are a highly recommended company through this site.

 

MD, a well known name throughout the G-Z community and well respected performance gains.

 

5/16 or 1/2 which is better??

 

better??? depends on what ur lookin' for, topend or mid gains??? make sure to go iso-thermal in any case.

 

OK thanks

 

Question, is it a plug in and forget mod? Or do I need to do anything when the winter rolls around? I am looking to get one as well and live in New Jersey where we get snow once in a while, but cold temps can get into the teens and even single digits.

 

the gasket, no... the coolent "on/off," yes. just switch it the "on" in the Winter and on cold(>55*) mornings.
