I have had the Apollo CAI installed on my 08Elantra since Dec07 and for 7,000km without any issues.

Its been taken off and put back on twice as I have taken it to the dealer for oil changes (45min to take off) … dealer provides oil changes for life.

The sound is similar to stock except at WOT where it sounds great even though it is a lot louder. I have noticed about a 4% milage benefit. My seat of the pants dyno show better torque.

WRT ECU overheating … manufacturers build to worst case scenario … that's why we are able to do mods that increase performance but really do not impact reliability in the environment we use the car. There would have to be really high ambient temperature for the ECU to fail with this mod. The ECU box heat sink is very large and the ECU does not generate that much heat.

I intend to keep using this CAI … love the sound and performance … not a big risk.

Without an actual dyno, there is no telling what the increase would be.

A flow test on the aftermarket setup vs the OEM setup should show if it is worth the money for the aftermarket setup. If there is little difference in flow rate I would not bother changing it. I do think the HD stock system is designed much better than the older Elantras and the new setup should be equal to the aftermarket if the panel filter was used.

Manufacturers design the system for a reason. Hyundai designed the OE air to cool the computer not just because of ambient temps, but also underhood temps, which can get 200 degrees or better. Computer equipment does not do well with that kind of temperature, even external temperature. The heatsink needs to be cooler than the internal temperature to be effective. 195-200 degrees is not cool enough to keep the computer happy. It actually heats it up instead.
