"the instalation was fairly easy.i had a little trouble getting the weather stripping on the filter box.recomend this be done at the factory.i noticed a increase in throttle response but have not seen a increase in fuel milage as i had hoped." —Alan W from Columbia, MO bought a K&N 77 Series Metal Intake Kit for a 2002 GMC Sierra.
"I put the throttle body spacer on my 2002 GMC Sierra 4.8L in about 45 minutes. The instructions were great. I noticed a better throttle response and a little more power in the midrange but nothing drastic. The 'whistle' sound is barely noticable, unless you are really listening for it. I have not noticed any gains in fuel milage yet. I am going to put dual exhaust on next, hopefully that will spice up the engine a little more!" —Bryan H from Scottsdale, AZ bought an Airaid PowerAid Throttle Body Spacer for a 2002 GMC Sierra.
