Airaid520-538 PowerAid Throttle Body Spacer

This is a repeat buy, simply because it's dependable and easy to switch out

I purchased this for my 2005 nissan titan along with a K&N intake. This product does make a whistling sound and in combination with the intake makes my engine roar. I was surprised with the increased engine noise. The Titan always had great get up and go but it seems to have a bit more, although that could be in my head:) I just put it on last night so I haven't seen gas mileage yet. The product was easy to install other than having some minor issues, not related to the product. I could not fit both the spacer and the intake without having to modify my fan shroud, I had to cut a portion of the top off so it would all fit.So far so good!

Installed with no issues in about 30 minutes on my titan. Used it for a few days with the stock intake while i waited for my K&N. I was looking forward to the whilst but at first it just sounded like my brakes are squeaking. When paired with the new intake it mainly get drowned out but you hear it working the loudest at around 2500-3000rpm when rolling l. Off idol i cant tell if its my intake or spacer but it sounds bad ass. Still not sure if i like the squeak yet but it did improve torque for sure. Good thing is i can get my money back if i want.Im adding this part a few weeks later. Grew on me, i love it now! Me friends keep asking " you added a turbo?" Haha. GET THIS SPACER!

Installing this guy is tricky. At least it was on my truck. The old bolts were locked in and one was stripped. The bolts for this are longer (they have to be), but made from a cheap material and very easy to strip out. Be careful when installing this. I am glad I have it, the idea of getting better gas mileage (I don't know how much/if it improved), makes me happy.

Installed on my 08 Nissan Titan. Very slight whistle when pushing higher rpm at low speed. Minor fuel savings. Don't care about added power if any it's minor at best. With the same driving patterns, and cold air intake, I've gone up 2mpg on average from a full tank on the highway. Not fantastic but not bad. 4/5 only because the bolts that are supplied are so cheap. Broke two just using a torque wrench to original specs.

Will not fit on 2008 Nissan Titan if using in conjunction with a 57 series K&N air intake system. The Airaid spacer adds an inch forward making the K&N air intake not fit anymore because of radiator shroud. I did not want to cut apart my shroud to use spacer....I figured I would get enough performance gain with air intake alone.

I definitely noticed a difference in mpg and increased hp. Only problem was one of the bolts were to short had to go to auto parts store and purchase a new bolt.

I wish AirRaid would put the item number on their products. I am very confident that I received the wrong item. Tried to install it and broke a bolt off in my intake. Three hundred dollars later and I returned this for a refund. Had more luck with my cold air intake filter system, so not all bad.
