Greddy vs Injen
What's up everybody Just got my 5pc Aero Five Axis body kit installed. I'm about to order a Borla cat back exhaust system but don't know which cold air intake to get?? I'm kinda leaning toward the Greddy or Injen but not sure which one is better?

I have to run a flow simulation to test my theory. But the short of it is I think that tube is altering the turbulent/laminar flow characteristics of the air past the sensor at the higher airflow rates in the upper rpms. And by doing so affects the MAF reading to help lean it out up top. But yes, all of this is rather moot when you consider that this can be compensate for on the tune. Just so we are clear. I am not disagreeing with your statements. I share the same thoughts on mostly all of it. I'm just sharing my opinion as to the effects of the small air tube.

Not sure if anyone's mentioned it, but the ECU has learning algo which is used in the first 100kms after an ECU reset. I wonder if the AFRs will be corrected by the ECU after the learning has finished. The Airaid instructions say to reset the ECU (disconnect the battery during install).

So with all the discussions about snorkels being on or off, I figured I'd post this : In the case of the AiRaid intake, some had said that leaving the snorkel on would mean up to a 20% restriction. Would you like to guess which run was with a high CFM carpet fan blowing at the intake (in addition to the hood being open and another dyno fan blowing) and which was without? I brought this up when @mechaghost posted his findings but some people were more keen to see better numbers then I think. Regards Bob @ Drift-Office, LLC |

Lol, I wasn't referring to ambient temp. I was referring to supplying cold air to an intake that isn't cold air. The AIRAID and Injen intakes both suck in hot air when the hood is closed and the car is warm.

Adding part of the snorkel to the Airaid
Would adding part of the snorkel help the Airaid?
This modification has the air entering from the colder side of the radiator. I realize it may reduce the intake size. I realize the air entrance isn't smooth or velocity stack shaped. Does colder air make up for the slight reduction this little mod may offer? Airaid made a mistake not extending the intake like the AFE, just my opinion. I'm going to get some fiberglass and mold a scoop for this Airaid that extends into the "colder area"

I don't have any numbers, ir data, but common sense would dictate the when the car is in motion the Airaid intake gets its air in front of the radiator and the motor, i.e. Everything that would be giving off any significant amount of heat.

So.... When is a company going to come out and make an aftermarket snorkel that is larger and more efficient than the stocker? Almost seems like common sense, it would convert all the intakes into cold air intakes...

I don't think it's that simple. Sure, colder air is always good, but cooler air won't help the fact that there is a bottle neck at the inlet constricting the incoming air.

Ok, I was discussing this with a friend at work. He said he wouldn't get an intake because it might void your warranty. I realize dealerships can technically use anything that isn't stock against you, but has anyone heard of someone getting denied warranty work because of an intake?

If it's too early and you don't feel like reading, the cliff notes is I saw an immediate gain in HP when I removed the snorkel, from restriction alone. Wasn't a huge gain... maybe 2-3 whp. |
