K&N Typhoon intake...so hot it burns the hand

elite130 · Jun 14, 2006

I got a K&N Typhoon intake from a buddy of mine about a month ago. I notice that after driving for a long time, the intake is so hot that if you touch it, it will literally burn your hand. My question is, is this heat hurting my HP more than the intake helping? In other words, I know I got a little HP from the intake, but am I losing more HP due to the heat? I know I have 3 options:

1) Keep the whole intake on
2) Take the whole intake off and go back to stock with a K&N drop-in
3) Remove the tube from the MAF to Throttle-body and put stock rubber intake on.

What do all you think?

what is a k&n typhoon intake? Is that the metal one they make for imports?

It is exactly like the FIPK, except it has the metal tube between the throttle body and MAF.

Here's a link to it:

Yeah, and also what type of metal is it made out of? Is it thin, cheap, chrome or is it aluminum, stainless? Take a pic if you can.

It says it is made of aluminum, which it is, but it is pretty thin.

Since we're hitting near 100* temps, I would take it off till late fall. I work downtown Denver and my car said 104* when I got in it. I think it actually hit 99* up there today.

I've ditched 2 metal CAI's for my plastic Demolet...first i had a BBK, looked pretty but got real hot...then i tried the C&L system. Just sold that and that got hot also. The plastic ones stay cooler.
The added heat can't help. I ditched my C&L because i didn't want any added heat with my Eaton Blower.

get the metal ceramic coated. I had my CAI pipe ceramic coated and it was way cheap, Its never hot now.

I'll give Lee a call, see what he can do.

good idea Trust me he'll hook you up with a good price

And spend more money on an inferior product? Nah, I'd go with the Demolet. (Actually, I did have the Densecharger prior to the Bullitt intake.)

The question still remains:

Does it matter that the pipe is hella hot? Does it affect performance at all? Anybody know of any tests that have been done? I would think that since the air is being sucked in so rapidly, it wouldn't have time to get hot ... just cause the tube to get hot due to friction. no?

Hell yes it makes a difference! The skin temps of the metal tubes probably reach 300*F. That is going to transfer heat to your air charge. Any heat, no matter how small, is undesirable. But given the fact that the delta of the ambient charge air temp and the tube temp is probably greater than 200*F, we're talking about a potentially significant amount of heat being picked up.

Not trying to hijack, but does anyone know where the intake air temp sensor is located (upstream from the intake we're talking about or downstream like around the plenum)? I just put my stock boot back on in place of the C&L CAI for the same "hot" reason and I was curious if I could get fairly accurate readings of the air temps with the Predator to compare the 2 intakes.

Amazing, I was about to ask the exact same thing. I have a Predator too and was going to do the same thing. Except, we may have a problem...I think the IAT became part of the MAF in 01 (but I'm not positive). If it is in the MAF, it does us no good. Someone please answer this question!

OK. So would this happen mostly at idle? I mean, would the engine be most affected by the heat transfer at idle, since the air is being sucked in slower? Also, do you have any idea of how hot the stock rubber deal gets? I'm guessing nowhere near 300*F?

It's been proven on this site that a bolted on stang shows only SLIGHT hp gains in the first place. To pick on the (in)signifigance of these intakes concerning exterior temp is pretty pointless to be honest.

I'm not trying to kill a thread.. but to take it all into context.. You wont feel a difference between a very hot exterior intake and a cooler one.

Though the theory stands.. if you want a colder exterior temperature on your intake.. go with plastic or rubber.

As far as CAIs and mildly bolted on stangs are concerned.. I'd go with the one you think looks the best.. thats the only thing you'll ever notice.

'01 Steed · Jun 15, 2006

Yes, we're talking about fractions of hp, but as a general rule when mod'ing, you should go with the best product. I think everyone would agree with that.

The intake air temp sensor (IAT) is located immediately behind the mass air flow meter (downstream of the maf). It is a separate sensor. This is only true for '01 and older. For '02+, the sensor is integral to the maf.

K&N Typhoon...keep it on or take it off?

Keep the intake on

Remove the intake and go back to stock w/ K&N drop-in

Remove tube b/t MAF and Throttle-body and put stock rubber intake on
