K&N Cold Air?

You wont get a gain. More noise, but thats about it.

 

Looks like it. You wont get better flow either. The OEM intake is pretty good. Unless you are going to do more mods, to work in conjunction with the intake, your better off saving your money.

 

Did you bother to read the OP has the 2.7??

 

It has no affect on the throttle response. THe throttle will still open the same speed, regardless of the intake you have. If an engine has poor throttle response, thats most always a fueling issue, rather than an air intake issue.

 

Alot of people think that, as they can now hear the intake, vs. not being able to hear it as much when stock. Ive had 2 1GR's side by side. 1 stock, and one with headers, exhaust, intake. They both reved the same. The way (speed) and engine revs is mostly determind by the reciprocating mass inside the engine. A lighter flywheel can increase the speed at which the engine responds to throttle inputs, but other wise, aside from major tuning, and corisponding mods, any difference isnt going to be perceptible without the use of some computer monitoring device.

 

The URD design is a good design. Personally, I think its how a "COld air" intake should be for our trucks.

 

Its the URD COld air AIR CONDITIONER intake!!!

 

Sure cutting the air flow will choke an engine. However, the new intake isnt forcing air into the engine. The pistons still have to suck it thru the same valves. The intake simply doesnt creat the amount of parasitic drag required to make it rev that much different. I can only asume the placebo affect is what makes people think throttle response is increased.
