DIY intake pipe mod

[teK--]

Metal = attracts and retains engine bay heat. Also replacing that pipe with anything else deletes the small resonator chamber which will affect Helmholtz tuning of the intake.

I would be interested if this goes ahead

I couldnt be stuffed welding the two together.
problem is, if you take the air box right out, it leaves a massive hole in the inner guard. I think that looks crap.

so i've attached just a 45degree elbow to the intake box with the filter on the end of it.

I'll eventually get a saw and cut the elbows to keep the standard airbox there.

Digging up an old thread, but i'm interested in doing this simple mod. Mainly for cosmetics
Just wondering if anyone knows the pipe diameter for an MY07 2.5i ? I measured but not 100% on what I got, inches is confusing lol.. I know its slightly bigger than 3" on the external measure..

Does removing the resonator if the pipe is replaced actually have any affect? (especially on a stock car)
If so, would any re-tuning be necessary?

I thought I would add what I did to my car when I first got it. This mod is long gone as I am now supercharged + intercooled, but from memory it was a nice little mod. It made quite a big difference to the engine noise (without the resonator boxes to dull the intake noise). I simply used some heat wrap on the metal tubing and even after a hard drive, the metal way ALWAYS cold. It is suseptible to minor "heat soak" if you are e.g. stuck in traffic

I logged a slight gain in top-end power that was significantly improved through tuning. Tuning is the way to get the most from an intake mod. For those chasing power and responsiveness, a tune is your best option. Also a lightweight crank pulley kit will make your engine feel sharper, almost like you've removed weight from the car.

Pulling this thread back from the dead. Had a look through the forums and couldn't find anything that was a straight buy and replace part that was not ludicrously priced. Came across this thread and it worked a treat!! Looks good, sounds a slight bit better but it seems to feel a little bit driving too. Seems to rev slightly freer. Cheers mate
