The stock intake gets heat soaked by radiator and sucks air in on the hotter side of engine bay. By relocating the maf and intake to the passenger side you can gain a good bit of Hp and torque if done right. U must extend the maf sensor wireing by a harness or making your own. I made my own and at first I had issues because the wires were not equal length and we're not soildered. Once I made them equal and soildered them really good and heat shrink tuned them it ran perfect. My buddy also tried it and he used to thin of wire at first and went to better wire and it was perfect also. .

I've done this in both 240sx and Nissan Frontier.

Basicly youl def gain power and your Iat temps are lower. If done right your maf won't give you any issues. You have two options. Buy a maf aka mass air flow sensor extension harness or make one.

Take equal length electrical wire you get at parts store the same thickness of what's in there now. Be sure each wire is equal length!

Cut cleanly each wire and get a soildering iron and soilder the wires on each wire to lengthen the maf wires. You have to do this because the stock maf sensor won't reach over to the other side of the engine bay. Basicly I took an eBay short ram intake tube off a Honda and cut it to length. Just play around with diff intake angles you can buy them cheap under 20$ or try pep boys or Autozone. I used a 20$ Autozone cone washable filter.

I ran it behind the headlight and I actually noticed much much much lower intake air temps ESP because the air was flowing into the intake from behind the headlight. I then made an air dam and ran some flexible tubing to it from under the car so it became a ram air intake.



The reason they did the intake from

Stock the way they did was for emissions and power restriction. Also a good Hp trick is use the nickel trick. Black off the metal tube coming off the exhaust that goes into the intake. A nickle fits perfect. Just cut the metal tube in the middle and slide the nut off and put the nickle inside it and screw back on. That alone helps a lot. All it did was recirculate the hot exhaust gas back into intake. No need for that

I thought this was a good explanation. That sounds like what I basically did, wish I had better pictures but here it is
