If that's the case, go with the Mugen airbox. As I've posted before -- no hydrolock, not crazy noise (although it's nice), no heatsoak, great throttle response, and still gets cooler air from the empty space in front of the radiator. And, they've just released an EP3-specific version, so you won't have to cram it in there like I did with an RSX version into my EP.

No doubt, the Mugen intake is nice when price isn't an issue.

Leland, ready for the EP3 version!!

Hehe... Well, I might have a buyer ready for the RSX one; just depends on whether I take his offer.

Just now found the pic of the EP3 box at Mugen's website, too. Looks like they made exactly the right adjustments to fit correctly into the EP's engine bay. There's a kind of hollowed-out part where the brake fluid reservoirs sit, and the intake scoop & mounting bracket are redesigned, too.

HMM.....

Since Mugen's site is so heavily Flash-driven, it's virtually impossible to link directly to the airbox product page. So, here's a screenshot, showing the EP box and the pressure drop graph (or whatever it actually represents; it's NOT a dyno graph, FYI).

That isn't for the EP3... I believe that is for the TSX.

The EP3 and RSX boxs look pretty much identical...

Yes, they're pretty close to being the same thing. I have the RSX box in my EP (got it a year and a half ago), and it has three fitment issues. The rear driver's side of the box basically sits underneath the brake & clutch fluid reservoirs, which makes securing all the screws very difficult. The lower intake tube is sized at the correct length for the RSX engine bay, which makes it too long for the EP's, which results in an uncomfortably tight fit. Lastly, the mount on the intake scoop is designed to bolt directly onto the Type-S's intake support bracket, which is angled towards horizontal versus the EP's nearly vertical bracket.

King Motorsports told me that the rear of the box was reshaped to make room for the fluid reservoirs, although it's hard to tell in the pics. More evident in the pics, the lower tube, scoop, and scoop mounting brace were redesigned to fit into the EP correctly.

If you want to spend senseless money on a name. Getting the best does not always mean paying the most. Mugen is no where near the quality level it once was. Still good products but not for the inflated prices. Go Mugen if you are doing your whole car Mugen (performance, aero parts, interior). Otherwise, don't waste the money. Everyone I have talked to is a Mugen *****, but again it is a name based on a past reputation, not because of the sheer quality of their products.

If you want a nice intake that will give you CAI gains, without risking hydrolock and/or heatsoak, all while maintaining that nice, clean, OEM look, go for the Comptech Icebox. Works in much the same way as the Mugen intake, but it pulls air from under the car instead of direct front-on.

Get the Mugen if you want, but get it because you like it, not because of the Mugen name, or because of the fact that people will see it and know you spent $700 on an intake. $700! That is almost as ridiculous as spending $900 on a Spoon muffler (not an exhaust system, just the muffler). Look at the testing the manufacturers have done for their products to base your decision. Just because a company is based in Japan, does not mean they make the best parts for a Japanese car. Any company, anywhere can do the R&D to make better products.

I understand exactly what you are saying and implying, but after seeing both the Mugen airbox and the Comptech in person... the Mugen's fit/finish/overall quality is much superior to that of the Comptech. Is it worth all the extra money? That is up to the buyer to decide...

Yup, and that's what I did.

Part of the Mugen box's cost comes from it being Mugen (not even I can deny that much), part of it lately has been because of the weak dollar (I paid something like a hundred bucks less when I got mine), and part of it goes into the fabrication of the box itself. Hand-laid fiberglass & carbon is more difficult and time-consuming than mandrel-bent CAI tubing.

So, what benefits does it have? Its materials don't radiate heat into incoming air like the ARC box or metal tube intakes (it's another reason why the OEM system is all plastic & rubber). The location of its scoop is safer than a CAI's and draws cooler, fresher air than either a short ram or the Comptech box. The bigger filter allows better airflow throughout the rev range. The box design, with its glossy smooth interior, helps retain the throttle response of the OEM intake, which responds quicker than almost anything else.

In most applications, IMO, the Mugen box is the best choice.

Not for $700. That's almost K-Pro. For an intake box?

Price is no object, right?

Spend that much fabricating, prototyping, test fitting, reprototyping, and -- finally -- finishing your own box.

BUT...

You can get a lot of the benefits for a lot cheaper by changing the intake scoop (something like the T1R duct), switching to a higher-flowing filter, and gutting the stock box (Hondata mod). That is my recommendation for someone on a budget.

Too bad that the Comptech box was never proven to gain well. The Mugen box is part of the 20-25 whp gain I've gotten on my car.
