I didn't put it on, so I can't comment on the install process, but so far I am very happy with this product on my 2003 V6 Tiburon (auto). It looks great on the engine, seems to fit perfectly, and is solidly put together. Things are more fun at the gas pedal.

8D

This is only the second mod I've made to the car, the first upgrade was a Borla cat-back exhaust system.

I was concerned about how the Cold Air Intake would sound, but no worries. There is a slight sucking sound when starting the car first thing in the morning, but that goes away after a minute or so. Cruising around town at normal speeds and RPMs, I don't really hear a change. In fact it seems to have quieted certain aspects of the aftermarket exhaust, and that's fine by me.

The only time the CAI sings is when you floor it- then it sounds mean, but it isn't overly loud. It also rained for two days with no hydrolock issues experienced.

Anyway, we did before and after dyno runs, here are the numbers with the CAI installed:

RPM +HP +Torque (vs stock intake system)

2900 11.53 20.46
3000 9.07 15.95
3100 3.05 5.25
3200 1.08 2.99
3300 0.90 1.49
3400 0.50 0.79
3500 0.60 0.93
3600 1.70 2.61
3700 3.50 4.98
3800 5.30 7.25
3900 6.20 8.43
4000 6.20 8.11
4100 5.80 7.46
4200 5.50 6.84
4300 5.00 6.08
4400 5.90 7.03
4500 6.90 8.04
4600 7.40 8.42
4700 5.80 6.37
4800 4.10 4.54
4900 4.30 4.58
5000 5.60 5.87
5100 5.60 5.73
5200 4.00 3.94
5300 2.70 2.67
5400 4.50 4.44
5500 9.60 9.28
5600 13.30 12.95
5700 10.50 9.67
5800 3.90 3.48
5900 0.20 0.24
6000 4.30 3.75
6100 5.30 4.47
6200 13.80 11.70

Seeing the stock intake system was sobering. It looks cheap, bulky, and very restrictive. The car is definately breathing easier with the CAI installed. There's $200 well spent!

My check engine light has come on twice now. The first time was about 2 days after the CAI install. I took off the negative battery terminal and that reset the light. About 2 days later the light is back on. Everything looks to be tight and installed correctly. The car drives fine, like always. Any ideas?

It is cold here, 15 - 32 degrees, could that be freaking out the computer?

After the CEL came on the third time, I drove to Autozone so they could check it. I don't remember the number, but the error code indicated low air input pressure. Took the MAF out, and one of the two thin sensor wires was broken. I guess maybe the shop damaged the MAF during the install. Put in a new MAF ($200) last night and everything looks good so far. Took it for a drive and had some fun.

Everything looks good so far...

Hyundai's in general respond well to easier breathing. RD tibs gain 13WHP from a good Catback exhaust. They can gain 11-13WHP from an AEM CAI as well. It really makes a difference driving a car after it's been free'd up.
