🔥 Enhance Engine Performance with Airaid 520-538 PowerAid Throttle Body Spacer for Optimal Results Review

Installed after installing a K&N cold air intake on my Nissan Titan. Even more improvement noticed. The whistle cannot be heard.

A waste of time, a waste of money, just like the fake Turbo Spin air intake that was the product of the TV ad, it was the same as a defective part.

I bought two of these for my father in law and my Nissan Titans. Easy to install, great sound! Does it give you more hp? Probably not, I don't feel any difference, but the cool factor of how it sounds is amazing.

Installing my 2004 Nissan Titanium in minutes made the K&N cold air intake sound even better. And felt throttle response and a little more power. I'll put it on dyno to see if there are full results.

I installed it with an Airaid 521-284 MXP, it's VERY tight, the gasket is pushing the TB out and now my cold air is touching the belt Fan. Plastic. I used to have all the stocks and I can feel the difference. The truck is definitely more responsive. And it meets CARB requirements. Installed on a 2008 Nissan Titan Pro4X.

This is a great product, before I installed it on my Titan I could barely hear a chirp from my rear wheels when starting off from a standstill. After installing it, my rear barks pretty well. Especially uphill I have a significant increase in torque. Do that! It's easy to install and costs $100 per win.

Will not fit 2008 Nissan Titan when used in conjunction with K&N 57 Series Air Intake System. I didn't want to cut my sheathing to use the gasket. I figured I was getting enough performance gains from the air intake alone.

This type is difficult to install. At least that's how it was on my truck. The old bolts were twisted and one had snapped off. The screws for this are longer (they should be) but they are cheap stuff and very easy to loosen. Be careful when installing this. I'm glad I have it, the idea of improving gas mileage (don't know how/if it improved) makes me happy.
