I tried a 3 inch CAI, but it threw a lean code, but a smaller diameter tube may not lean the mixture that much.

Yes, the airbox air does cool the ECU. Hyundai designed it in that way for a reason. Will it overheat the ECU? Personally, I chose to keep the airbox stock, but install a panel filter. I was not going to risk damaging the ECU (an expensive item) and have trouble down the road.

Why are you so sure? The ECU's heatsink cooled by lots ambient air at maybe 30-40C vs under-hood temperatures of 50-60C or more with close to zero air flow... and it's an expensive item to replace! Unless Hyundai did that unnecessary change only to make us question the wisdom of CAI's... that would be sneaky... maybe there's an ECU temperature sensor to detect use of a CAI... maybe it all explodes above 50C!! AaAAAah!! I dunno man...I dunno

There is a 4-5 page thread on EXD about the Incus SRI and the ECU cooling issue.

Hyundai did place the ECU next to the open port for a reason. I'm assuming it is there to cool the ECU. Also, the ECU mount bracket also holds the stock airbox. It would look funny if a CAI were on there and this big bracket holding the ECU is still there.

I'm not sure any of us have enough experience of the HD to say this with such certainty.

Exactly. I'm not going to chance it.

Since the original poster is in Syracuse NY, I thinking it probably wouldn't be a problem. There are few days in the summer there that it gets that hot. It the OP had lived in say Phoenix, I would think that would probably be a much bigger issue.

But as Cclngthr said, until we know more you are gambling with a very expensive, and must have piece of equipment.

That piece of equipment does run/monitor more than the engine on the car. It also is something I don't want to recommend yet. I have the HD, and still don't want to mess with something that controls things that are critical.

I am not willing to chance it.I will not use the cai untill I talk to to the dealer ship.the only way I am going to chance it is if the dealer will warranty the ecu and I do not believe they will.this car is a pain to mod!

*SIGH* . . .what happened to all of our Pioneers? THe ones that took the chances to find out what worked? It seems people just want it on a silver platter but don't understand the sacrifices people like Jay, Ford and the like did to make it happen so long ago.

Basically, until some one tries it out, we won't know. Period. Colin and his doom&gloom theories about how cars are to never be touched are way to the left, while Joe's carefree "it'll be fine" attitude is to the right. The real answer is probably inbetween.
