JonW said:I'm sure the CAI has to help some, given the fact that the factory airbox is so restrictive. But I'd say that the 91 octane tune provided the bulk of the power gains. I'd like to see dyno numbers with JUST the CAI and and no other mods or tune.

read the article
In the article it states that they did a couple base line pulls
1st pull........... with the stock airbox less the HC trap with "NO TUNE" and the #'s were 261rwhp & 281 rwtq.
2nd pull.......... stock airbox, no HC trap + 91 octane tune and the #'s were 271rwhp & 289rwtq.
So it is safe to say the 91 octane tune on a stock setup is good for 10rwhp & 8 rwtq.
They tested the AFM (Anderson Ford Motorsports) CAI and it yeilded 16 rwhp with NO additional tunning (meaning this pull was compared to the 2nd pull as stated above)..........Proof that this particular intake is good for more than just a couple of hp's.
This quote from the article sum's up K&N's performance #'s over stock
"K&N promises 15.26 rwhp at 6,000 rpm, and our testing showed an 18-rwhp and 15-rwtq gain over our "no-tune" base numbers (1st pull), which is outstanding power for a kit on a naturally aspirated Mustang. With the MD Motorsports tune in place, the car picked up an additional 3 rwhp and 3 rwtq, showing this system has just about maxed out the capability of the motor to ingest air through this size inlet tubing"
And these are only two of the many intakes that were tested.
Fact of the matter is a good tune is good for about 10, maybe 15 hp.
An Intake which requires no tune is good for about the same.
And together gains are seen anywhere from 20-30 hp depending on the particular combo (tuner/CAI) that you get.
Believe what you will, but you're mistaken if you think the CAI's don't add any power over the stock airbox.
