I bought that intake. I LOVE it. It sits right behind the front bumper. It sounds awesome. Gives the car a meaner sound. You can actually hear the suction when you get into higher RPMs. The install overall wasn't too bad, it took about an hour or two. It involves removing the front drivers's side tire and the shroud inside the wheel well.
You know how the the lower part of the bumper has the middle grille and the two smaller grilles on the outsides that are solid plastic. The intake sits behind the small plastic part on the driver's side.
I'm actually thinking about popping that out and putting a grille that will allow air flow.
isnt that what your supposed to do. TO pop out that little plastic thing and let more cold air flow into the filter. My friend has an aem v2 CAI for his 2004 accord v6 and it scream and its located exactly where you are talking about and his has the removed piece of plastic.
K&N always had great build quality and excellent filters. If I was getting an intake, I'd be with them. Weapon-R used a dyno error to market their stuff and treated people on other forums like imbeciles - not a good thing when you are trying to establish a reputation for the company. I wound not touch their stuff with a 6-foot pole. Overpriced half-ass made stuff.
The advantage is that you go from a roughly 2.5" OD intake to a ~3.75" OD intake in less than 5" from the filter box. You use your regular filter (recommend K&N, TRD, or Green filter) and filter box. Costs about $15 to $25 with most parts from Home Depot or Lowes. What I like about it is that the power band feels smoother up and down. I really like the way the engine spools up. Most likely the same effect you would get from the Typhoon. Note, I am claiming no HP gains, but the car is more responsive and the engine sounds less strained when mashing the pedal hard. I am truly loving it.
The disadvantage is that it can never look as good as the Typhoon. Another disadvantage is that you have to make it by hand. Third disadvantage is that you have to cut the existing intake.
It worked nicely on my Z3 and I like the feel of it on the tC.
I don't know when crutchfield started carrying them...I just stumbled across it by accident looking for an installation kit...the intake is still on backorder from K&N with no ETA......great....well at least it's crappy weather here, if it was nice I think I'd be a little more pissed.
sorry to bring up such an old topic, but i just bought one and after i bought it i found out it wasn't CARB approved. so its in the mail and i'm just gonna sit on it until they approve it. so just a little FYI.
