is the pop charger worth the extra $ over the k&n filter? Will i notice a difference between stock, k&n, and the pop charger? And is there a big difference in performance from k&n and pop? Thanx (need it quick, i am about to go buy a k&n filter)

 

the cone will make it alot louder at hard accelleration but you wont feel any difference.

 

anyone know how many horses they each add

 

I don't know about anybody else but I feel a difference with the POP Charger. Seems to have better high-rev acceleration. The sound of it when you tromp on the gas is pretty impressive.

 

I'll prove that a pop charger does something once I get my 14.7 this week. I've had a pop charger on for one week and I know I'm feeling a difference. If i can pull another 1.9 60' I'll have it for sure...

 

K&N panel filter: +0hp
Cone filter: +3-4hp (more with other mods)

 

Turbo Magazine dynoed the K&N panel filter to have a 4hp gain. There is definitely an improvement in throttle response and revability of the engine with the panel filter.

 

maybe I need to bolt the stock one back on to find out what im missing

 

what car did they put it on... because it was not a maxima.

 

Right. If that's the case, our pop chargers and cai's are getting a lot more hp then.

 

It was a 5th-gen Maxima, a few months ago.

 

Ha,
I heard Org stickers give ya 5hp

 

The scuttlebutt on the 5th Gen board is that the K&N filter may give some increase in horsepower, but not the 4 HP quoted in the Turbo Mag dyno run. Apparently using an OSCAI with it does make a bigger difference.

The Maxima.org stickers have been proven to add 5 HP, but the additional weight curiously enough cancels it out EXACTLY.
