The Injen intake comes with a very well put together list of instructions, pictures and all. This guide will show you how to modify the intake parts to fit your geartronic car; the intake was designed with a manual C30 so many things don't line up quite right.

Intake Pipe Mod
I don't know if this is an Automatic thing, but the stock intake pipe has two hoses and the Injen only has one input. I got a metal T hose connector and some extra hose to create this setup (one of my hoses loops around to prevent any harsh bends that would restrict flow):




ECU Bracket Mod Be patient, this is tricky to properly (safely) install.
First thing to do is undo the bolt that holds the clamp shown here, remove this entirely so you can move the wire tubes around as needed:






Also remove the clamp here, reattach it upside down so that it holds the wire tubes downward:




Move both the ECU electronic connectors under the green striped wire tubes. (I only have one of them moved in the picture below):




Move the coolant hose (the long hose on the bottom of this picture) so that it'll be on the inside of the ECU. If need be, twist any other hoses/wires away from the ECU so they are NOT touching it; you won't want them to melt from the ECU heat output:




MAKE SURE that nothing touches the transmission linkage (directly below where you'll be mounting the ECU). I had to bend my bracket some to hold the ECU higher, it initially pushed down on the linkage which cause issues when shifting between Park and Drive (thank you mkd28 for helping me find the problem):




Heat Shield Mod
You'll need to cut or bend the right side of the heat shield so that it clears all the automatic transmission parts. I bent mine back and flattened it with a clamp:




If fitted properly, you should be able to still attach the two screws at the bottom/inside of the heat shield:




Everything else should install straight from Injen's instructions.

Other Intake Mods
Cut an opening in the battery cooler tube:



This throws more air right at the filter and ECU (see the cut opening in the top of the picture below):




Open up the front scoop so that it actually scoops in the air (I plan on making the funnel larger and moving the horns):




Bought a silicone connector to reattach the two stock intake pieces:



Funnels the air better:




Remove the resonator from the rubber tube that leads from the intake pipe to the turbo, it comes out with a good tug. I did noticed a drop in boost pressure when I simply had the resonator removed, so you'll want to replace it with a straight pipe or fill the resonator holes and replace the stock piece. This is what it looks like with the resonator removed:




Final result:



----Review----

At low RPMs there is a bit of a turbo whine. This could be amplified due to my delete of the intake resonator and removal of the under-hood insulator.

At mid to high RPMs there is a significantly lower "grumble." It's an intake tone, not an exhaust tone.

No need to get a blow off valve with this intake, you'll hear the turbo psshh every time you come off the gas.

Throttle response has improved immensely. They advertise +19hp, I don't have before/after dyno proof, but there is most definitely a gain (just not sure if it's a full +19hp).

All in all, I'm very satisfied with the product. Well packaged, easy to follow instructions, sleek design.

Always ;) I clean it every month.

And thanks! Still trying to keep money aside for the timing belt next year, but the intake was a gift :D

OH Good - a - Vid

Did it look like the MAF was farther in or out of the Air in the Intake Tube ?

Good Sound , and I'd add that intake hose from Viva to Turbo - it has a slightly larger ID and a Nice Taper Design : Tornado Effect . ;)

The MAF is further back in placement, but it appears to stick into the Intake pipe about the same distance as the stock set up.

I definitely will be adding the intake hose eventually. I just didn't want to spend any more money right now.

Yeah... I'm sure there's before/after dyno runs of the Injen intake somewhere though. Possibly on C30World too.

Actually I have never seen an independent before/after dyno with Injen intake, C30World included.

As yoou didn't make one either I'm concluding you primarily got it for intake sound? :D

I'd point the - Cold Air - more along the Sheet metal - It will be pulled and in just don't want to see to much Water on the Starter Area . ( Running In Rain )
After your sunroof episode you see problems with water just about anywhere, don't you? :D

For starters, I didn't want to spend the money for a dyno run right now. But yes, I got it for sound, looks, and MPGs. Basically a cosmetic piece, I don't care about making an automatic car "fast."

Yes, I just had it turned a little from when I put it in. I'll fix that though, thanks for pointing it out!

Well, it certainly looks nice - I hope it sounds as good as well.. :)

Which part? Both plastic parts are from the stock intake. The blue silicone connector is from Advance Auto Parts, it was $8. I didn't trust the stock rubber connector thing to support the weight of the 90° pipe.

sorry I didnt clarify, I was reffering to the silicone connector. Great write up, looks great.

hey there - thanks for the great write-up. I'm interested in putting an injen in my C70 and was wondering how the unit fit around the strut tower brace. I have the Volvo OEM one installed in my C70 (though it did not come with one, I put it in). From your video it looks like you had the OEM bar in the "before" picture and another aftermarket bar in the "after" picture. Am I right, and if so did you do this in order to fit the new intake? Any other thoughts on intake fit vs. strut bar?

I just so happened to install the EST strut brace the day after I installed the intake. But the Injen intake will definitely fit under your stock strut bar. I inquired the same thing before I ordered the intake, here's a picture of it with the OEM bar. This is a bad angle, but the intake is not touching the strut bar (though it is close).

Nice install instructions!

Yes, all P1s (C30, S40, V50, & C70) are more or less identical. Our engine bays are the same because we both have T5s.
