Hello and thanks to all for your excellent contributions…. Well now I can now also contribute by informing you of the cold-air intake that will soon be available by/at Injen.com.

My car was use to develop the FX35 cold-air intake; Injen specify needed a AWD to ensure proven performance. Injen had my car for two weeks as they developed and test several intake versions. Because I work in the area of Injen’s R&D building, I would pop in and witness their scientific testing procedures as they tested my FX on a 4-wheel dynometer. The results is 9-10 hp increase!


Currently, Injen is awaiting CA smog approval before they release the FX35 intake (3-4 weeks).

I am having trouble posting the installed intake pictures; if someone would pm me I would send you the pics for posting.

I take it that it'll eliminate the need for a z-tube?

Little slow on the draw...just saw thr pics so my question is answered. Very nice.

 

[Ak1nza]

Very nice. Too bad I already have my Z-tube and popcharger.

That's going to cost upwards of 240 bux as well though.

I have never taken a liking to CAI because of the nuisance factor. Getting to the filter and having to clean it often is really annoying. Also, hydrolocking is always a problem in the winter months. The bypass filters suck and i've read horro stories with them.

Agreed. Install is a b1tch and so is maintenance of the filter. It looks like you can make it into a short ram however (assuming there's enough clearance for the filter to fit in that spot). Maybe they should offer a short ram version also.... probably do better w/ sales.

I love that the MAS is integrated into the alum tube. Looks so nice & clean.

Thanks to Esemes for posting Injen’s cold-air intake pics.

Regarding Mushutofu’s comment on Injen’s intake/filter placement may cause hydolocking; Injen intake is designed to minimize hydro. You will notice on picture #2, the intake filter can is designed for disassembly at the front gasket. In fact, Injen’s R&D specialist stated that much of their business is “back east,” therefore; the conceptual design process begins with the hydro issue in mind. In fact, Injen’s R&D specialist demonstrated - in about three minutes - how to move the intake filter higher during heavy rains and reconnect the filter at the top gasket. Further, the front gasket designed also enables rapid filter maintenance and/or replacement. If Esemes is willing, I ask that he post the pics that illustrates Injen’s downsloping/filter location.

As I indicated in my original message, Injen’s technicians designed and tested several different intake versions on my FX35 over a two-week period. Each intake version was attached on the FX; performance measured and recorded on their 4-wheel dynometer. This tube design with the filter location distant from the engine enables maximum cold air induction. Moreover, several non-essential restrictive air devices where eliminated. I recommend a visit to Injen’s site at Injen.com so you may appreciate Injen’s legitimate and rigorous testing procedures.

I know I sound like a sales rep., - I assure you I am not. I was waiting for a lunch order at a restaurant near Injen’s complex, when several of Injen’s employees (Injen’s logo on their shirts) stop in. As we waited, I asked one of them when they would be selling a cold-air intake for the FX35. Coincidently, he said his company was in fact looking for a FX35 AWD for development of a FX35 intake. The agreement was they kept my car as long as necessary; in exchange, I get to keep the intake. I further agreed to provide Injen with verbal updates regarding “real-world” performance situations. After driving/pushing my car for two weeks, I will say it is an excellent product!

Finally, I was evident to me that Injen’s technicians methodically and legitimately achieved increasing the FX35 performance capability – I know because I witnessed there testing procedures; see the improved gas mileage and feel improved acceleration!

I am looking forward to Injen’s developing the FX35 complement exhaust system!

I just hate how there's nothing for the '45s ...!

DITTO!

HAve you ever had a fx343? I was reading your post then realized you were biased. CAI's are nice but they are a paint to take care of.

...CAI's are nice but they are a paint to take care of.

****, I knew they were difficult to clean, but ya gotta paint 'em too???

I have a 300# FX35 RWD. you made mention that the CAI was specifically tweaked for AWD. What if any downside might there be in installing one in my RWD?
Thanks in advance

 

[MustGoFastR]

I don't see how being RWD vs. AWD would have anything to do with the intake at all. The only difference in terms of performance (HP) is in the drivetrain loss. Airflow is airflow regardless of the drivetrain; it's going into the engine. Performance gains should be identical on RWD and AWD. I don't understand why the drivetrain it was tested on was even mentioned; just a source of confusion.

 

[Sweet Fx]

I agree with the above post. I think AWD was mentioned to
"cover all bases" so their is no confusion that it fits All FX35s.

 

[TEX35B16]

Y'all are right this from Paul Ho at Injen- Thanks--"Fuel and ignition maps are identical on both AWD and RWD models the only
difference would be the driveline loss when you dyno a vehicle. The AWD
models will lose a average of 25-30% and the RWD will lose a average of
12-15% of power to the wheels. The gains will be all the same but the power
to the wheels will be different on AWD and RWD."

Keep in mind those are general numbers, not FX specific numbers. I think than RWD range is a bit on the low side, esp. with our heavy-ass 20s. Even Zs run around 15-18% drivetrain loss.

Intake fans - I asked Paul about the potential moisture and added noise with the proposed Injen CAI for the 35 and I like the way this guy thinks-- Here is his reply-"It really depends on how much moister you are talking about but as for my
car during the rain I have no problems and my car doesn't even have the
fender liner to protect the intake from direct splashes during the rain
season. Which is not a good idea to do but I don't really care. Most of the
moister that will go through the pipe will evaporate before it goes to the
motor due to the heat from the pipe. Best of all the intake can convert to a
short ram in less than three minutes. The noise level is tolerable but that
really depends on your tolerance. Personally I like the way the intake
sounds on the FX35 because the car sounds as mean as the car looks.

Are these beasties that much louder than say the Stillen/Z tube combo?
