2002 Sentra CAI for GXE (now in progress)?

So i've been looking at CAI's and from all the one's i have been looking at they say for SE. I have a GXE, are the intakes the same for the GXE and SE?

 

[audio1der]

No they're not. I'm not familiar with the MAF for the 1.8, but thed routing is different. You will have to modify any CAI not designed specifically for your application; Might as well make your own. Lots of good articles can be Googled for DIY CAI.

 

[hova04]

yeah their not similar. They do make an injen brand cai for the gxe but its pricey and i heard their not all worth the price.

ok so i got an OBX DIY CAI for the 1.8l with no couplers or maf adapter (getting that from pepboys/autozone).

My question is, what size couplers will i need? The piping is 2.5" tapered to 3", do i get 3" couplers or 2.5" couplers?

you gotta fit the pipes together. you need to figure out what end is connecting to the maf adapter 2.5", what end connects to the air filter 3". so you need couplers for the rest of the pipes in between those, not sure how many bent pipes you have. the only place you may not need a coupler is where the air filter mounts, you need a 2.5" coupler between your maf adapter and your first 2.5" pipe.

Just get the spectre couplers from autozone or whatever, if it is too big they tighten anyways to fit whatever size you need. I can tell you that the MAF housing that autozone regularly carries is not the proper size, even after asking them if it would fit. Pep boys might have one though. MAF was way too big to fit inside the hole of the housing. What you can do if you don't care, is take a hacksaw and cut the MAF housing off the stock pipe, and use 2 of the couplers to hook it up to your DIY CAI. Doesn't look any different than if you bought a black plastic aftermarket housing, the couplers cover up the hacksaw marks anyways, and I like how the couplers look. But if you can find a chrome/alluminum aftermarket one that fits, go right ahead, but the hacksaw method works fine. I have a DIY intake as well.

I was not going to play around with the parts trying to buy the right one and ending up needing more and more or a different one, so I ordered over $100 worth of different piping, just so I had all the angles and straight pipe, etc, that I needed, and returned all the rest that I didn't. It's not like you lose any money anyways.

Just got my OBX DIY cold air intake (ebay). Just so people know, it comes with a 2.5" pipe between the throttle and MAF, and a 3" pipe between the MAF and the air filter.

Pepboys and Autozone wanted $18.99 for a 2.5" Spectre coupler. Screw that ****, i even work for Pepboys and even with my associate discount it wouldn't bring the price down enough to even match a 3" coupler they have for sale available at the floor (for about $7-$8.99). SO I just put in an order for 2 couplers for 6 bucks each on ebay.

I am a bit worried about the couplers for and between the throttle and MAF, the fitting at the MAF looks a lot larger than the one at throttle. It will all come to place (hopefully) when i am putting everything together.

Also, my lower pipe (the pipe between the MAF and air filter) there is no bracket or arm to install onto the frame of the care, it's just bare bent pipe with a temp sensor hole. Can anyone go into detail of how their's is installed?

You have a 1.8l too? the connecter that meets the MAF and Pipe for the air filter, is that a 2.5" or a 3"

The CAI DIY kit i got is this one:

As you can see, no arm or bracket for the pipe between the MAF and Filter to bolt onto the frame, solutions?

I personally wouldn't hack the MAF housing, especially if there is any chance you may need to switch back to stock.

If the MAF adapter is the right size tubing as your MAF, the only issue would be drilling out the holes on the adapter to make sure they match the smaller group of holes for the 1.8 MAF housing. This is how most MAF adapters I have seen are setup.

If it worked for you, great. Just not the way I would have done it. That is the real thing, everyone has their own way of doing it and if it works for you who cares!

 

[i68k]

there are maf adapters for both 1.8 and 2.5 motors that bolt right onto the maf without drilling, not sure if there are any metal maf adapters for the 1.8 though, i know theres plenty of plastic ones.

from pic you are right, the short piece with vacuum fittings goes between the tb and maf, the longer pieces should connect to the air filter and most likely tuck behind the battery/headlight area.

Took my short ram off as the oil in the filter was messing with the MAF, How is every one else getting around having to clean their maf every couple of weeks?

 

[triniwi]

Please don't put a cold air intake on a 1.8 just remove the air intake resonator and it will work better and get a Nissan oem filter.

Read around u are going to f up your maf just remove the air intake resonator.

It sounds like you may be over oiling your filter. I had this happen a few times myself, typically right after cleaning and oiling the filter.

I do not agree. I ran either a short ram or a cold air intake for well over 130,000 miles on my 1.8 and still had the stock MAF sensor. I did have to clean it a few times with crc MAF cleaner but no problems other than that. Hell I would recommend cleaning that MAF sensor sometimes anyway.

OK just giving some advice. I know the MAF is sensitive that why I'm saying that. I myself just toke off the intake resonator and I'm got more power and, sound a lot nice at the same time

And also I just by OEM filters

It is very sensitive, you are correct. The thing I should have added on my previous reply was that the intake, whether short ram or cold air, needs to be mounted or secured in such a way that it won't shake the MAF sensor to death. I think that is the biggest cause of failure for these MAF's.

Definitely agree about removing the intake resonator. That was one of things I did within the first 20,000 miles of owning my car. You are right, it certainly sounds meaner without the resonator and it should allow it to breathe a little better.

You should put a short ram or a cold air intake on and hear the difference!

I'll think about it and nice talking to u

Will this one work

That one is for a 2.0 and I think the pipe is different. I would say get one for a spec v and just make sure you have the right MAF adapter. I used a cheapie eBay one with a k&n cone filter.
