Default Gp Moto Intake Elbow

I recently received my Intake Elbow from GP MOTO. However, It didn't come with any instructions. Has anyone installed this mod yet themselves? If so, do you have any pointers? Thanks.

It's fairly easy and straight forward. The one thing, if I remember, I used the bolt/stud from the factory piece to use on the GP Moto elbow. There may be a little cutting/grinding or something to get it to fit in the new tube. I can't remember exactly what I did, sorry. Just take a look at it with both pieces out and you may see what I mean. Good luck.

Just look over the intake snorkel removal intructions on scoobymods. It follows the same basic procedures for getting to where you need to be to install the elbow.

I don't think any grinding is really necessary for the install. At least I didn't do any when putting mine in.

Thanks for the help. Did you guys experience any noticeable gains in performance or sound with this elbow?

All it changes is the sound. The stock piece with the resonator cut and the hole taped off is the same thing, just cheaper and, well, with duct tape instead of a complete plastic part.

No significant airflow change, just the removal of the resonator. A sound mod only. Many have the same effect from removing the resonator/elbow altogether - just drawing air from the fender well and plugging the "scoop" hole.

just running the airbox with just a hole in the airbox and everything else remove could affect the MAF
a velocity stack is needed if you wish to go that route.

Never heard that before. I know many do that, and I've never heard of any problems, but that's not to say there weren't any.

No it's not. There has never been any proven data that says it messes with the maf reading.

If you are worried about it though go to Lowe's or HD and get a 3.5" rubber 45* elbow. Cut it in half and feed it onto the airbox and then out in the fender well. $5 CAI.

i found couple thread in the past about snorkle removal..
probabily not enough proof it would cause significant problem
but why risk it over $20-30 worth of parts..
as far as i know running CAI or shorty intake could significant affect your MAF and could result in adverse affect on your engine and turbo.

Personally, I don't see the need to do anything - mine's bone stock - good for more power than I'll ever modify my engine to produce. However, to each their own - if you like the noise you get when you remove the resonator, go for it. Want a CAI? Sure. Use cheap PVC? Great.

I know aftermarket CAIs are known to cause problems, but that's more change than simply removing the resonator/elbow.

Heck, the MAF is after the filter (airbox.), so I don't see how doing anything before the airbox can have any significant effect. (Unless you do something that results in a lot of water injestion.)

I have no direct evidence, but as I said before, many have simply removed the elbow/resonator, and I haven't heard anyone noticing a problem.

I just installed GPMoto elbow today too. Don't notice any additional noises nor power, but I also put on some +1 rims and rubber that are a little heavier than stock so that might negate any minimal gains in the first place.

I noticed a hole in the bottom of the snorkel chamber; i suppose to drain any water. I wonder if that was a crucial purpose of it that the straight through elbows lose?

I do have one install QUESTION though:
the foam gasket: does that go on the inside of the airbox or outside? I notice the ridge on the elbow which I suppose should be inside the airbox's built in rubber gasket. But what about the gpmoto elbow's foam gasket?

Here's a thread on the intake silencer removal.


It mentions a lot of the issues you guys are touching on. Out of the 157 people who voted, only 7 actually experienced trouble after this mod.

Most people did the mod in one of 3 ways:
1) Hack the silencer and leave it
2) Remove ram-air and plug the hole in the fender
3) Use Rallitek or GO Moto elbow or something similar


Personally, I did #1 and it's fine.

I went the ghetto route and cut the entire bottom off of the intake box. All that is left if the uppermost portion that has the clips on it. Kind of like a homemade blitz induction cover. The filter is fully exposed. Did it make a difference? It made the intake loud as hell. Best of all, it was free.

The foam gasket goes outside of the airbox. It seals between elbow outlet and the airbox inlet. The ridge on the elbow is the stopper for the gasket. I had that question as well. Did you notice any difference in sound or performance? I didn't notice any difference at all in either category. A little frustrating.

Where did you guys get your GP moto elbows. I am assuming that you are talking about the peice that goes between the airbox and the inlet pipe. Not the scilencer delete elbo. I don't want the latter.
Thanks in advance

We are talking about the snorkel delete option. It re-routes air from the inlet pipe directly into the airbox without tumbling into a silencer first. If you are interested, you can find them for $40 @ www.jscspeed.com The shipping is cheap and extremely quick. If you have any trouble installing, feel free to ask for help. It took me about an hour total.

yep, I got mine at jscspeed too. You can get it at fastwrx or even through a nasioc vendor.

I didn't notice any sound or performance. Honestly, I noticed more sound from the K&N panel, with which I am greatly dissatisfied with the fitment and just ordered a Green.

Install took me a bit longer because I couldn't get a push clip out of the underside liner. I actually had to drill it out because I broke the head. I hate those dang things. I also noticed that the screw it came with had a small head. You might want to have a washer on hand; I didn't and I think the head started slipping into the plastic of the elbow.

I'm pretty disappointed with this mod and might just put the damn snorkel back in. I'm not considering running w/o the scoop at all so the elbow would've been the best shot.

All that work just to put the snokel back in?! You're brave. I'm not happy either, but I figure that if anything, we are at least improving efficiency and gaining some sound at higher rpms. If I do anything now, it would be to skip the stock intake and get a SAFE short-ram (If there is such a thing). My original goal was to keep the safety of stock but gain the sound of aftermarket. It seems we can't win.

Brandon,
I emailed GPMoto directly about the foam gasket. Here is what they said (a bit contrary to your research):


The foam donut is to be installed inside the airbox.

Crap...Well, with the time it took to install, I think that I might just leave it the way it is also. I don't imagine there will be a problem. It's sealed either way. Maybe I'll call and just have them send me one more gasket. Put one on either side of the airbox wall.

haha. yeah, I don't think there should be a problem, especially since it's on the dirty air side. Although my rubber airbox gasket didn't quite seal because the GPMoto elbow is thinner-walled than the stock piece.
