I got bored and bought a short ram induction kit from someone on the ATR forums to try it out. It sounded nice but suffered from heatsoak (as expected really). I ordered a 45 degree silicone bend and 18cm metal pipe from ebay to extend the filter down into the wing.
I have to say I'm very happy with the result. No heatsoak and thus better responce, nice sound thats not TOO loud and best of all, it was cheap :)

I take it that's in the Accord?

Looks like you did a good job of installing it, unlike most people I know that just slap it on the intake and leave it at that!


I quite like that sort of induction kit, I'm sure my missus has something similar on her renault clio (haven't bothered to look under the bonnet), as you can hear a rather nice sound coming from the engine, that isn't the echaust blowing. Don't know if it improves performance, but the car is nippy and nice to drive with it in :)

I was going to mention that it could potentially intake water when going through large puddles etc. But judging from how steep the pipe seems to angle, it should be fine.

Will just make it soggy. :p

Yeah thats on the Accord.
In the first pic the wheel arch liner is removed, once its back it locks in with the plastic at the front of the bumper to form a splash guard. The only way it would suck in water is if I went into a REALLY deep puddle, by that point I'd prob be more worried about floating away down stream :)

I was ultra bored today and also painted my brake calipers and Tcutted the car, will fire up piccys tomorrow :)
 
I'd still be cautious of sucking in water. I few GTi6's have died by doing this :o

Looks like a very good job though. Would be interesting to see the car do back to back runs on a dyno :)
 
how is this not going to suck in water when driving in the rain? Splash guard or not, in that position its going to get wet. Not something i'd want on my car.
 
Because it sits behind the arch liners. Mine did anyway, sold the car ages ago but had no problems for the months I had it like that:

My Hyperflow kit is placed in a similar manner:

After over an hour on a rolling road, intake temps hadn't gone about 25oC, and were mostly below 20oC.

Hmmmmm.... Water gets everywhere when it's raining... That said, it shouldn't be too bad as it's on the drivers side of the car, which is good. If it were on the passenger side I'd be more worried as that's the side you drive through all the roadside puddles in.
 
Umm, good idea in theory but i'm not so sure, firstly we have the damp / wet filter problems, then we have the 'its going to get clogged up more' issues, and finally more pipework before the throttle body, this could potentially hurt throttle response.

AEM make a air bypass-valve to eliminate the chance of hydrolock from a wet CAI.
 
I did the same thing with my Prelude, it was originally under the bonnet next to the battery, but I moved it to exactly the same place:

Increased noise, appeared to improve response/performance slightly (though that could be placebo effect due to increased noise), and in the 6 months it was there, never once had a single problem with it, and there's no signs of water damage to the filter.
 
So tempted to do this on the teg, more for noise than anything. Hydrolock scares me though :(
 
Drex, a lot of people over on the ctr forums are using Injen Hydroshields and seem to be recommended. Not sure how much they affect airflow.
 
I did a similar thing where I got some metal ducting and ran it from my front grille up straight in to my airbox. As i'm driving the cooler air from lower down is forced up the ducting and straight in to my smoothed airbox.
They reckon that the set-up I have coupled with a green cotton high flow air filter offers more airflow that the K&N Typhoon kit which costs over a hundred quid.

Cost of my set-up?

£6.99 :D

Just googled them, looks like a good idea. As long as I don't lose power with with the CAI/Hydroshield combination compared to the stock airbox, I'll be happy. I just want the noise :D
 
If it's anything like the Type R (it's probably the same airbox) then it has a couple of resonators you can take out, do that and add a less restrictive filter like a Spoon foam one, or a K&N and it should feel more responsive. It won't sound much different though.

If you stick the cone in the front bumper, like the OP, it'll sound absolutely awesome, I can guarantee it:D

Other than that you could check if GruppeM do a carbon box/intake for it, expensive but about the best kits you can buy. Or Mugen, but i'm pretty sure thats £400+
