cool, Can I add this mod to what I have done already?

It looks like its talking about modding the section after the MAF up to the throttle body. Is that correct? Or is it mainly talking about the airbox?

thanks

I attempted it today but to no avail.

I think the throttle body may be at a different angle on the 3.2 as it looked like a 45 degree bend would have fitted much better.

Next week I am going to source a length of air-seeder hose in 3" diameter that should fit. This will be easier to install and should create the same end result.

After pulling the hose off, I believe the only real benefit to this mod is removing the "muffler" on the intake hose. Not sure if under wide open throttle it will make much difference, but it should benefit low end torque. Of course the sound will be an improvement as well.

P.S. Just looked at Pedro's site, the boxster he did this mod on is different to the 3.2.

The only tip I can give at this stage is remove the oem hose first and then buy elbows with angles to suit. 90 degree bends did not work for me.

My hack was done on my '98 with the 2.5L engine.
Model Years '97 through '99 are the same.

In 2000, Porsche introduced a new throttle body (with e-gas) and it's shared by the 2.7 as well as the 3.2 through 2004.

The angle of the throttle body's mounting is different as well as the diameter of the cross section (it's smaller).

I'll try to find (a victim) with a newer Boxster so that I can document the hack on them.

Happy Boxstering,
Pedro

Actually PVC is very good.
It's lighter and a better insulator than aluminum.
It's also slick inside.
The only downside is that long-term it will tend to crack because of the heat from the engine. But it'll be a few years. Enjoy!
Happy Boxstering,

I just replaced the intake tube.
I left the airbox intact.
