Diamond Blue 4S tip

My car is a 2003 C4S. I got the Schnell CAI today. It installed easily, as advertised in about 15 minutes. There is a hose loose now. It used to have a fitting on the OEM "snorkel". I think Loren referred to it in his air filter DIY as the sucking jet pump connection:

"Loosen the hose clamp on the throttle body and remove the connection of the sucking jet pumps (not present on early cars)."

Is this a problem? I think I may have spotted it taped out of the way with electrician's tape in someone's post about his CAI.



The loose hose is overlapping the red of the schnell snorkel.

do you hear a difference or feel any difference in the performance of the car.????? although i like the orange look.......

Well, I was waiting to hear from someone who has this mod with the extra hose. I don't want to screw anything up by driving it if it is a problem.

I'll let everyone know, though. I'm not expecting any performance improvement, just a throatier sound.

I decided to go out for a drive. Any increase in power is too subtle for me to notice. But it sounds great at full throttle. Reminds me of the intake noise of a friend's 73 Vette when the secondaries opened. The sound at part throttle/while cruising is unchanged.

No CEL or adverse affects from having the "sucking jet pump connection" (whatever that does) hanging loose.

JimW - I think thats a hose that only the tiptronic cars have. Though I don't have a tiptronic, I'm pretty sure it still needs to be hooked back into the orange thingie. FYI...take a peek at this link for the directions on installing the K&N intake - steps 28-31.

Here's a pic of an evo intake on a tip (notice the hose going into the intake)

It looks like I will take the Schnell off now. I really appreciate your researching this point for me. I wouldn't have guessed it had anything to do with a tip.

Thanks!!

The Schnell intake came off and the stock intake is back together. I think it was under 10 minutes this time. I may look at the K&N or EVO, since they have a provision for a tip car.

I put one on mine yesterday it sounds great. I have a tip but I do not have that little hose. If there is any HP increase it is 2-3 you would never feel that you need a dyno. Well worth the $100.

One more thing DO NOT PUT THE HOSE CLAMP ON THE PLUGGED HOLE!! It is for back pressure relief if you have a backfire there is no where for the pressure to go.

So does the kit work on Tiptronic cars or not? I have an 01 C2 Cab.Tiptronic and was looking for a good CAI. Is this kit pretty much the same as the Fabspeed but about $100 less?

Actually, I have an EVO CAI on mine that was put on sometime back, and it has the hose connection for the Tip, but it's got a rubber plug on it becaue I have the 6 speed.. I guess back then, the kits were pretty much interchangeable with the exception of the hose connection for the Tip.

I just ordered the Schnell CAI. I asked the tech about the Tip hose and he said they supply a cap to cap it off. It is pretty much the same design as the Fabspeed but $100.00 cheaper. They said you dont use the hose with the CAI on their system.

I also went with the K&N drop in filter for $69.00 they gave me free shipping.

I also have a Schnell CAI, actually I got mine from Jim above (original poster), Thanks Jim... I believe the Schnell's design is the same as the Fabspeed, actually not sure what is the real difference though, Oops... The fit and look is nice. I have it for a while now and so far so good, without any CEL or other issues (knocking on wood ). I love it. On Fabspeed website they show you how to install that little extra hose, I think you just drill a little hole for it and stick it in, not too bad. Good luck with your new CAI and enjoy...
Cheers,
