DIY instructions on installing the stock air intake?

[Edwardo]

Hey guys,

I have an Ingen air intake right now that the previous owner installed. I also received the stock air intake with the car. I would like to put the original intake back in.

I did a search and could not find any informaion on this. I also checked Danoland for info.

Is this in the service manual? If so, what section/page. I could not find it.

Thanks for any replies.

As far as I know, there is no written DIY help available for installing the OEM intake. Check Service Manual page 11-112 and 5-22...there's not much help in the manual either. Assuming you have all the right parts and peices, the DIY shouldn't be too bad. Is the OEM side vent tube still in place?

Funny you should ask b/c I just got done reinstalling the oem airbox myself. You don't need instructions, it's pretty self explanatory even for those not mechanically inclined. Angle the box in w/ inlet that connects to rubber flange (inside of fender coming in from side vent) downward & connect that first. In other words, the writing on the sticker will be facing to the left rear fender. Now connect the accordian like tube to the outlet to the engine & tighten the metal ring fastener. Wiggle the box into place (so that the 3 holes on the built-in brackets align with holes that accept them in engine bay. Lastly, clip the surronding hoses into place (built-in snap tabs on airbox lid). That's it!

I would add that it's even easier if you take the top half of the box off first. Not as cumbersome than installing as a whole assembly.

Guys,

I appreciate all the responses. I am going to try to tackle this project this weekend. One thing I am worried about is whether or not I have all the parts. I have the big box(with the air filter in it). I also have a tube(the one that curves). Finally I have a few bolts. Hopefully this is all the parts.

I am a bit intimidated by the project because I don't want to hook it up wrong and then have dirt particles getting in my engine and ruin it.

I will try tomorrow and let you guys know if I am successful.

Thanks again guys!

Edwardo, ther are no parts, the brackets are built into the box, you just need the bolts, if you don't have them, you can get them from your hardware.

Not to be TOO anal about this one…but because the NSX’s aluminum construction, most of the steel fastening hardware needs to have a dielectric coating to protect against corrosive galvanic action between the steel fastener and the aluminum body. I’d stick with using OEM parts when it comes to using fasteners on the NSX. The Service Manual page 5-22 shows the required fasteners (quanity:3, 6x1.0 mm bolts in this case) and their torque settings. Note: if you look at the bolt description on page 5-22 you’ll notice a star, which denotes that these bolts should be of the dielectric coated-type. Please look at Service Manual 1-12 for more info about using nuts and bolts with the NSX. I know this is anal, but using fasteners with this dielectric coating is important, especially if the car lives in a wet or humid environment (or the car gets frequent washes).

For tools, you’ll need a 10mm socket and a few sizes of extensions, like a 6” and a 10”. I think a wobble extension is really nice to get one of the bolts. Take care not to over tighten the band that secures the flexible rubber thing to the throttle body. If you’re concerned about debris getting past the air filter then after the box is installed, remove the filter and vacuum out the intake area and inspect the filter for any big particles.

DanO, that's a good catch & you're absolutely correct about the corrusion of generic nuts & bolts against aluminum. Edwardo, everything lines up, so just make sure the rubber ducts fit around the inlet/outlet. Good luck.
