I recently purchased the K&N Typhoon Cold-Air intake. It may not be legal in New York State. Does it have any effect on my emission system?

 

[Grabber2012]

It has no effect on your emissions system or emissions, but are you really asking us whether you should plan on returning it to stock every year at inspection time?

We sympathize with you, living in occupied territory.

I do not mind switching back-and-forth once a year. My question is: Will my "check engine" go on and will I have to clear the code monitors with my OBD-II scanner?

 

[Grabber2012]

No. It returns everything that was on the stock intake. See recent review by J Orbit: http://www.allfordmustangs.com/foru...h/420313-k-n-cold-air-intake.html#post3868353

I admit that J.Orbit is correct. While working on my nephew's Mustang assembling the K&N parts to themselves were a bit of a pain. However his car is not California Emissions compliant. He has absolutely no issue. As long as the Cal-OBD II diagnostic array overlooks the prosthetic windpipe, switching is a mere cakewalk.

There is a difference in CARB (California) requirements and NY along with other states following CA emissions on new cars.

As I've understood it you don't need CARB certification on mods in NY as long as you pass emissions and did not remove cats.

I'm in NYC and have had 4 cars with CAI's that have passed inspections at gas stations and Ford dealers without any comments from the inspectors.

Like others have said just save all the stock parts just in case....

 

[JohnCappola]

I quoted your (pmr2000's) comment to my nephew on Facebook. He will now feel unashamed for talking me into buying the CAI. Your comment is reassuring and appreciated.

 

[pmr2000]

You should not get a check engine light on a no-tune required CAI, most MAF's can adjust 10% up or down before throwing a code just as if the filter was dirty.

You shouldn't have a problem getting inspection, don't bother swapping both to stock unless they complain.

K&N Typhoon Cold-Air Intake

A parameter of 10% plus or minus mass-airflow is somewhat tight. The K&N ruturns a 5% increase in horsepower. I hope it takes an equivalent increase in the amount of air .

well it sure wont give you 15 hp
maybe 2 just saying

 

[JohnCappola]

You have an Air Raid CAI w/ a DiaboloSport Intune. That level of sophistication is way beyond that of the K&N. Have you ever thrown a "Check Engine" light?

 

[pmr2000]

A tune should take the CAI into account so should not throw a code.

A CAI without a tune is more likely to throw a code.

 

[mustangkid9234]

Never thrown due to cai
But a airraid and the like wont throw a code with out a tune...
A steeda will im almost positive.... its something to do with a bigger maf reading... as in the tube is bigger

K&N 69-3529TP Cold-Air Intake

A K&N 69-3529TP appears to be more like the AirRaid than the Steeda. The intake tube seems to be about the same size as stock. The SCT3015-S3 is a bit of an overpriced investment just to tune a CAI.
