Your cart is empty.The Airaid PowerAid Throttle Body Spacer is developed to enhance off-idle torque, from 800 RPM to approximately 3,000 RPM. It incorporates a patented helix bore, which causes a spinning action of the incoming air-charge as it passes through the throttle body spacer. This improved air-charge carries all the way into the combustion chamber, producing a super-atomized mixture, which produces tremendous gains in mid-range power and overall combustion efficiency for better fuel economy.

I installed this with Airaid 521-284 MXP, it is a VERY tight fit, the spacer pushes TB out and now my Cold Air is touching the belt fan plastic.I had all stock before and i do feel the difference. Truck is definitely more responsive.And its CARB compliant.Installed on a 2008 Nissan Titan Pro4X.

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!

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.

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.

It's a great product, before I installed this in my titan I could barely get a chirp from my rear wheels at a dead start. After I installed it my rears bark pretty good. I've considerable increased torque, especially while climbing hills. Do it! It's easy to install and worth the 100$ bucks for the gains.

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!

I put this on my 2006 NIssan Titan. As far as I could tell, there was no improvement or change in engine performance at all. I removed it. Instead I installed a Banks Ram Air intake. With that there was a noticeable improvement in engine performance.

My only complaint is that the mounting bolts that come with it are aluminum. The factory bolts you replace are brass. Other than that it's all good. I also like the whistling sound. It makes me feel like i'm in a cummins turbo diesel.
