An intake is only going to make the difference of about 5hp on a good day so your best bet is to just get an intake that is going to make yur car sound good and keep yur engine clean.

 

it maybe a simple question but that dosent mean its a simple answer whats the propose of this car what year ?

 

Install a filter and drive car

 

I bought two for the 370Z. Wash and oil every 10,000 miles. In the long run its a money saver over OEM filters. These filters will last the life of the car.

I have the JW pop charger in mine and wouldnt go any other way. Makes the car sounds awesome at high idle and i noticed a big difference on pull even thought it was a 10+ HP increase.

 

I would be highly surprised if a dyno showed anything more than 2-5 HP to the wheels with a PopCharger. But they look and sound good. Pretty sure I saw a thread a few years back that showed the best gain on the DE was with a K & N drop in though, still only 5 HP at best.

 

how in Gods name is this thread still open.

 

you basically just stated "it's pointless to buy a full intake because you won't see much power gains, but buy a complete intake anyways!"



OP, just grab a k&n air filter and call it a day. no need to spend $2-300 on a brand new cold/short air/ram intake even though 80% of the users on here probably have.
