yes, I did a tech project two years ago on stock intakes, cold air, and a modified stock intaking showing that you can increase the intake manifold pressure by using stock parts. It was not a huge gain but it did increase over the CAI, and temp was lower as well because most CAI retain the heat and transfer to the incoming air vs a stock air box.
Anyways those fans in front of the car on the dyno is so it wont over heat, it does almost nothing for the intake, the velocity of the intake is much higher then what the fans can put out.
Bottom line your right no dyno time no real numbers all just BS, either way alot of stock intakes are good, non I've seen in under 40,000 cars seem to be worth much when it comes to performance.
Just for a side note, short ram intakes normally dyno higher numbers then CAI on the dyno. But in real life the extreme heat under the hood reverses that.
Either way a 1.8 is not going to gain much, I'm still kinda pissed that in 2009 Toyota has a VVT-i motor making only 130+ hp, when Honda back in 1988 had a crapy Integra 1.6L twin cam making 130hp... You think Toyota would have come up with something alittle better in the last 20 years... Why did they get rid of the XRS 1.8 motor? Just lower the compression for 87 oct gas and call it 160hp 1.8L that gets same mileage as our 130hp vs.
