Intake manifold spacer questions

I'm sure this has been answered but I am new to the forums and the search didn't give me what I was looking for. Can anybody tell me specifically what I will need for this mod? Space, gasket, and longer bolts is my understanding? Also, if you could supply part numbers or where to get them I would appreciate that. Thank you.

1 of these:
P2R J Series V6 Intake Manifold Spacer

And 2 of these:
2003-2012 Honda Accord V6 Thermal Intake Manifold Gasket

The spacer comes with the bolts.

Awesome thanks. The bolts was the part I was unsure of. This will fit with not milling ?

No milling necessary. Unbolt the intake manifold from the runners, and the spacer goes in between the manifold and runners. P2R has pics in the link I sent you above.

Check my post out in the 7th Gen Performance section.

If you are doing the spacer, you might as well do the manifold and throttle body along with it. I am presuming you have a CAI?

That manifold spacer is a waste and the only gains are from the full sized one.

Full sized actually has the worst gains out of all possible sizes.

Furthermore that post lost 4 hp peak and gained 5 tq peak.

With the correct size, and boring it to the right dimension, then boring the runners to the right dimension, you can gain the usual hptq of ported runners, then an additional 5-10 on both hp and torque. Without losing anything.

Also properly sized spacers will cause a flatline at the end of the curve, and not a downcurve. Somebody around has one of the dyno pics of my sold upper end builds, torque peaks then goes straight flat for the remainder like it should.

So sure buddy, that was exactly the right argument you needed to make to disprove that a non-stock height has the most gains.
