I was just wondering what filters all you guys are using. I am currently using the Monster Flow filter, but I am going to install the Apexi Power Intake filter tomorrow. I am also going to do 3-4 runs with each filter to see which yields the best gains.

 

cool hope it turns out diffrent

 

doubt you will feel the difference in power just from a filter. I did notice a difference in sound. K&N is louder than Monsterflow because I think the foam on the monsterflow acts as a muffler that dampens the resonation

 

i have K&N. but i always considered switching to a JWT or stillen filter because supposely they have better and bigger air-flow velocity than K&N. but probably just 1-2HP difference. i say go for a K&N for now because it is washable. it'll last for a good amount of time.

 

I already have 2 Apexi Power Intake Filters. I am putting one on today later in the early afternoon. I have a g-tech and will try and get some consistent runs for E.T's and HP/TQ. Just looks like on the monster flow there is no room for any velocity. Apexi filters are very very well built.

 

Stillen is a K&N

 

All of the filters are washable, all you gotta do is get the recharger kit from K&N and wash it twice a year. Also yeah the Stillen intake is the same ****, and is made by K&N. Although I always wondered how the K&N filter will sound different from the Stillen filter which have a little different shape and form. Did anybody try a little experiment, please let me know.

so is the JWT. All washable.
You'll notice a difference in sound that's about it.

 

Let us know how it goes. I was gonna do the same test yesterday but nobody with an Apexi showed at our dyno day.

 

What is the part number for the K&N? I want to change mine soon too because I cannot stand the foam!

 

Ok, I did some tests tonight between the Monster Flow Filter and the Apexi Power Intake Filter. I had 1/4 tank, 91 octane. Just installed the Apexi Filter today. I got a new personal best. Previous personal best was as follows.

I let the car sit 15 mins between each run.

Well Im not sure this proves anything, but th Apexi Filter does sound different and it feels like it pulls a little better down low.

 

i wanted to get apexi but couldnt find one cheap enough . I have K&N and i have a stillen filter but i dont understand u guys when u say stillen filter as a cold air intake. I'll take it stillen makes more than one type of filter for maxima's that i just dont know about because the one i used for hybrid setup seems way too big to fit in the fender area....or can it?

 

for the heck of it you should run with no filter for just one run ans see what time you get

 

I have a brand new in box Apexi Power Intake Filter if you want one.

 

done that , had no choice really but when i put the k&n back on the car felt like a turtle , those filters have alot of resistance,does anybody have a pic of apex intake filter

 

i wonder if the velocity stacks on the JWT and Stillen make any difference? i have a frankencar with the k&n, and i think it would be better with one.

 

haha, just noticed there were alot of mad-max's around now

 

three in this thread alone

 

What are you asking for it?

 

K&N. Who else has a lifetime warranty?
