I did a search and found that some of you had the check engine light come on after the install. It just went for me after 100 miles of driving it with the new airbox mod from Fabspeed. So what are my options?

1) Let the computer relearn it and hopefully it will go off in another 100-200 miles.

2) Pull the battery cable, reset the computer and see if it happens again?

3) Go back to stock?

3,000 miles since I installed mine..no check engine lights. I would not assume that the airbox was the cause of the light.. I'd get it over to the dealer. Perry

At least 5,000 HARD miles with mine plus a bunch of other mods and no CEL for me

To those of you that have the Fabspeed airbox, what are the noticeable (sound and speed)changes?

Carrera Rod

a little better sound. probably not much gain in HP/Torque but the power curve is much smoother.

Light is yellow, caused by the mod for sure. I guess I'll just ride it out until it resets itself.

you could be waiting a long time...

Had the fabspeed intake for 5k miles and never has triggered the MAF sensor. Now I have the airetek high flow one and it hasn't yet either. It may come down to the MAF sensor being contaminated which is entirely possible especially installing. I don't think by leaving it alone will solve the problem but who knows but if it does readjust that's great. You may put back the stock one and see if check engine lite triggers the the MAF is definitely the problem. Regards. Mike

No CEL for me either after 6 months with the Fabspeed/ BMC filter/ sealing of the hot air intake holes in airbox bottom.

Did you call Fabspeed and let them know of this problem? It's not cool to let the check engine light stay on, you never know when your O2 sensors might go or even other sensors.

My check engine went on after about 100 miles with my FabSpeed air flow mod. Had my dealer put the car on the computer and there was a MAF fault. The dealer said it could be a bad MAF, so they back ordered one. After almost a 3 month wait and one day before Thunderhill Track Day they installed the new MAF and did a diagnostic check on the computer and the readings indicated that it was running lean and my Tech said the check engine light was likely to go on again. Since the engine management system goes into a protect mode when the check engine light goes on I went home and put the black plastic screen (the one that fabspeed says remove) back on and went back to my dealer and we ran another diagnostic check on the computer the readings indicated everything was perfect. The car ran awsome the next day with new Porsche Sport Exhaust and the screen is still on and no check engine light alluminated.
I think some cars will like the full air mode and some don't.
Try putting the black screen back and drive your car three or four trips and tell us what happen.

I'm going to give the car another 100 or so miles to see if the light goes off. If it doesn't, I'll try putting the screen back in.....

Porscherenter

Went a few hundred miles and no luck so I put the plastic mesh screen back in and dis/reconnected the battery. After 300 miles, no light.....

Told you!
