Has anyone had any experience with one of these intake systems? I'm either going to buy that or the SLP one from neweraperformanceparts.com.

 

Don't know how good they are in the GM world, but in the Nissan Titan world, they're pretty good.

S&B had some revisions to the MAF sensor location in the tube due to CEL, but performance wise, IIRC only the Injen (at almost $120.00 more) out performed it.
Very good gains.

 

Hmmmm sounds like that the S&B is the way to go then, hopfully I can get one before too long, thanks for the reply.
