I am not to sure if anyone has this part or if anyone can help me make a decision about this? There is something called a plenum spacer. Its being sold for $191.95 and it claims gains up to 10hp to the rear wheels, Also better throttle response. I havent seen any threads for this nor have I seen anyone mention that they have this simple bolt on. Can someone give me some advice or if anyone has this bolt on can you inform us on how it works? Does it really work? and is it worth it to add on with a cold air intake from injen?

Besides the previous 47 “plenum spacer” posts, this is the first I’ve heard about it.

 

Search my friend.. and you WILL FIND YOUR ANSWER!!!!

 

the spacer basically increases the volume of the stock plenum, more volume means more air goes in. i think it's 1" raise, or something like that.

 

Then can someone tell me whats the best one to buy and how i can keep my stock strut bar?

 

I have the SKUNK2 Spacer. It's the biggest of them all but you have to raise your hood and say bye bye to your strut bar. As for a 10whp and responsiveness increase, it sure feels like it.

If you want to keep your strut bar and not worry about your hood look into the
Motordyne spacer. All 5/16" spacers fit with the stock strut bar and engine cover.

Or get the crawford cast plenum and strut bar. Crawford Plenum

 

I think when someone starts a new thread, a pop-up window should open asking them whether they have tried searching for it yet. Not that many would pay attention to it. Oh well...

Sorry man, I always hate saying this, but seeing the same threads over and over again, it gets annoying, even though I haven't been here all that long. Hope you can get the info you're looking for.

 

test pipes?

 

I istalled the AAM Spacer which is tappered .500 in front ( where you need more air volume) and .250 at the rear and was able to keep my stock strut bar ( had to build spacers to raise it).

 

I like your setup. What did you construct the spacers out of? I'd like to do the same.

 

im happy with the motordyne spacer.. it comes with spacers for the strut bar too

 

I used 6061 T6 alumminum x .250 thick and I came up with .200 clearance between the strutbar and the plenum. not a one problem..I can really feel the dif.in hp. around 4000 rpms and up..
the kit from AAM comes with spacers but they are just washers, which they work ok but i like what I did (more area with my spacers)..

 

question...
is your intake supposed to be that way?

 

That is one good looking engine bay.
If I read you right, you got just shy of 1/4 clearance between the Plenum top and the stock bar BUT if you use the supplied spacer, it will still clear but not as much?

What kind of gap would you say you had with the supplied spacer?

Sorry if this sounds stupid but is 1/4" even enough clearance?
Seems to me that the engine 'jiggling' on it's mounts could eat that gap and the plenum could tap the bar - right/wrong?

I have been looking into this mod because it really intrigues me since it looks like an inexpensive and easy to install way of getting the engine darn close to the magic 300 HP mark.

Besides what the car must feel like with the extra power, one can say they have 300HP and justify the statement.

 

DON'T GET THAT POS SKUNK2!!!! Stick with hondas a-holes!

 

Yes just shy of 1/4 between the intake plentum and the strut bar and I too thought that would not be enough, but that is not the case, cause I have no problems with the plentum hitting the strut bar during rev ups. However I did have to remove the two rubber inserts on the hood to clear the strut bar when I close the hood. IMO these are simple inexpenssive mods and I think I am running about 310 hp at the crank..

 

If you are refering to my intake K&N filter, yhea that`s how is installed. the center has filtering element too and it`s concave to create an air damm.

 

no heat shield?
