Intake spacer question

[RedThunder]

Would this spacer, 17108-RDJ-A00 give a 6-6 a bit more midrange torque? I've noticed it on '05 and up Pilots, Ody, and Ridges.

It would be a fairly inexpensive thing to do, 2 gaskets, studs, bolts and the spacer, all for less than $100. Will it clear the hood on an Accord tho?

TL guys are doing it, but they are running into hood clearance issues. You can do the "can crush" test on your engine to see if the Accords have enough clearance. Reports look promising, better low and mid range response from the people that installed it.

What about the openings in the spacer? Are they port matched for the stock Accord runners and IM? I'm curious to know about that but I would assume no since those engines are .5 liter bigger. I have a thermal spacer from Outlaw engineering but that is made for the 7th gen. No real gain in hp but it definitely keeps the heat down.

Looks like the TL guys are getting some pretty nice torque gain, but all at the expense of cutting their hood bracing, propping up their hood with spacers or taking the hood insulation out. I'm not sure it would be worth the modification to get the torque gains unless you're really eager to start cutting and removing stuff.

Maybe Paul can fabricate us a custom one at the right height that would give gains but not require cutting or removing anything hint hint hint lol.

I read through that article too. I wonder if it would improve over my Outlaw engineering one that would be a more noticeable increase. I would definitely be in for that.

How thick is the outlaw spacer?

[six6]

can someone please explain how a little spacer is supposed to gain that much power? and y didnt honda do this if it was so worth it?

[aprevo15]

hmmm i think ima do this mod.

does anyone have the part #'s for the gasket and the longer bolts?

[otsb708]

It increases the torque range on the pilot, and mdx.

If this can be proven that it won't hurt the high end rpm hp then I'm all over it. If Chad and Todd get this then I'm all over it also.....

[six6]

yes i understand it increases torque range (which i dont really believe), but how? how does it work

[otsb708]

Well if you don't believe it then why would honda put it on the pilot and mdx where the extra torque is needed...pretty obvious......

[six6]

correct, but why wouldnt they put it on the tl/accord then?

to cut cost? also maybe extra torque isn't as important to accord and tl as it is on the pilot and the mdx.

go down to around middle of page, someone did a dyno on the tl. +7.2 gain on torque is good. i want this now.

[six6]

how much are they? 20 plus shipping?

[aprevo15]

well you still need to buy bolts and gasket. but i believe it still gonna be under 100 bux easily.

i am reading that thread right now to get all the part #'s i need. lol.

[Kschwiggy]

u might also need longer intake maifold bolts


edit- well i guess chad and i posted at the same time


from the AZ thread:

"20 mod my ass.... . Try $70 +tax pricematched to Delray Acura @ my dealer.

spacer: ~$20
2 gaskets: ~$36
9 bolts: ~ $14 " you should only need to buy 1 gasket though

[aprevo15]

here's his dyno sheet. courtesy of acu-rate on acurazine.

New Dyno #s with IM SPACER
New DYNO #s:

Mustang DYNO:

Note, both runs were done on the SAME dyno

No SPACER= 280.6 whp & 246.9 wtq ........(dotted line)

IM SPACER= 281.3 whp (+0.7) 254.1 wtq (+7.2) .........(solid line)

thanks for that info. now i know exactly what's needed.

[nadracer]

Bolts from acura whatever seemed to be the pain in the pootie from this besides hood adjustments. But since this was taken from a mdx, pilot engine why couldn't the longer bolts and studs be ordered from those cars.

[otsb708]

I want, I want...

[Kschwiggy]

does anyone know how much difference there is with hood clearance though? i talked briefly with paul about it and we'd have to measure to see that it fits under our hoods without the intake manifold hitting


someone do a can crunch test like they did on AZ haha

[aprevo15]

well i have the cf hood so i have a bit more clearance than the oem hood i think since the bracing and stuff isn't as big as the oem.

also i don't mind using hood spacers to raise up my hood a bit. again because i have a cf hood, the spacers will look alright compared to having spacers on oem hood.

yeah the can thing was smart. lol.

[Accordian]

I'd probably have it milled down so I didn't need spacers or anything. Like it said in the thread, $20 at any reputable machine shop.

[aprevo15]

get it todd. NOW!!! lol.

[Accordian]

Lol I told you people I have no self control when it comes to this stuff! I'm seriously considering it. I just have to read the thread a little closer since I could only skim over it while at work. Damn this work stuff lol.

[Milan]

I've read about two pages so far on AZ. Will this work with the 6-speed dual-length variable runners?

[NVA-AV6]

Yes it will, let me do some mesuring tomorrow AM and I will see what we can do to get good clearence. I have a couple Oddy/Pilot ones here and of course can get them from my local Acura place and machine them down to fit if necessary. Kai is right we only need one gasket, worst case get some copper spray a gasket a lay down a layer on both sides of the gasket.

[Stevo405]

im assuming you will have to port to match already ported IM and runners??

Nicely enough I measured it before I installed it.



Its about a quarter inch maybe a little more. The IM gasket Outlaw provides is about 1/8".
