Yes. As long as you order the one for the correct year model, you should be fine. You will notice a big difference in performance and sound. Good luck. I love my setup!

 

I've run my car with and without a filter and there is NO measureable difference in ET or MPH. Period. It's all in your head. A filter is a filter.

Kloogy, wasn't your 60' siginificantly worse with the Injen? A .3 seconds difference in 60' can account for a solid .5-.6 seconds and 2-3mph difference in the 1/4 mile, especially if the car short shifted in 2nd. What was your 60' with the Injen and then with the other intake?

*EDIT*

Nevermind, I found it. Your 14.8@94 had a 2.25 60' and the Injen 15.3@90 had a 2.39 60'. The 60' difference in 60' alone will suck out .3 seconds and a good 1-2mph. With the same 60 foots, the performance between the two intakes is within .2 and 2mph which is within reason between hot-lapping runs, especially with an auto (harder to get consistent shifts). Unfortunately you never ran twice with the Injen so we'll never know if it truely was the fault of the Injen. There just isn't enough data here to say that the Injen is truely junk.

I never said it was junk. My car felt like **** when I ran it . Well, I just posted my opinions.... to each his own... we settle these things at the strip anyway !

 

Hey, cali speedway opens this saturday if you want to check out your times. When are you getting nitroused again?

 

For those of you who have this filter where did you buy it and what was the price? I am tired of my K&N, it doesn't have the same kick it did 5k ago.

 

You can purchase the APEXi air filter through Steve at FrankenCar Performance

 

Steve did do dyno runs and the Apexi gave 4hp more than the K&N. As far as "a filter is a filter", that's got to be the dumbest statement I've heard in quite some time. The Apexi filters out considerably more dirt than the K&N. A car is just a car so why not buy a Hyundai Elantra?

 

Whats wrong with an Elantra??

 

my friends got an elantra and its fun to race. he thinks with his 5 speed he can get me off line the, but of course he cant. the warranties are nice on them but you really do need the warranty. his odometer and speedometer broke at 21k.

 

Does anyone remember the site that had K&N filters on the cheap? I remember a site a while back for filters that was a ton less than @ a store. Anyone?

 

Filters are very comparable....so basically "a filter is a filter". K&N is the leader in aftermarket automotive filtration systems and basically started the craze. I would like to see some second party data stating that the Apexi filters air better. I personally would trust K&N over Apexi because of their years of experience in racing, particularly in Off Roading(Baja).

I still dispute that the Apexi gives any hp over a K&N or JWT. Removing your filter at the track does nothing, so how can a different filter do anything (unless it is dirty)?

 

well after reading all of this, i think i might get the filter and pipe. quick ? before I do, are the "supposed" HP gains going to be there with stock exhaust. Also, it seems in the pics that most people have removed the funnel that brings air into the air box. wouldn't it be better to leave it in place to bring in colder air?

 

I posted this link quite awhile back. Why do you think FrankenCar offers this filter
http://www.mkiv.com/techarticles/filters_test/2/

 

here it is:

If K&N floats your boat then I think you should stick with them. I've had both and the Apexi is a considerably better made filter. I'm not doing the search here to find the links to the comparisons from 3rd parties, but if you so wish to there are several reviews here that show more hp and better filtration.

 

Guess you've never dynoed a car before. I've seen swings in power of 5hp between back to back runs if the motor isn't cooled fully. How someone can honestly say that a difference in 2-3hp on the dyno with a different filter can be called a gain is beyond me. When looking at the final numbers, we're talking about a difference of less than 1% in power. There is a thing called dyno error and heat soak.

When good filters are compared to one another, a filter is just a filter. K&N, HKS, APEXI, Greddy, etc are all good filters. Some filter better than others, but their performance in terms of HP/TQ is the pretty much the same.


Dave

 

So to briefly reiterate myself, does anyone know of the site that sells K&N filters on the cheap? Also, what was the part # for the filter that goes with the Berk, or in my case, BerkEnCar?

 

Agreed. I had problems with my K&N, resulting in a horrible drone, kinda like a ricer civic with a oil barrel muffler and it was under all rpms. The car also seem to give out of hmmfff around 5-5k rpm. The K&N only had 5k or so miles on it and the filter wasn't very dirty. After installing the Apexi, these problems went away and MY car feels like it pulls a tad harder all the way up to redline without any of the drone sound. It just sounds great and it's not oiled!

 

I also am a firm believer in the heat soak b/c I have lost over a tenth and a mph by running back to back at the track. The thing that puzzles me is when steve dynoed the apexi and then with no filter at all and only gained .4 whp over the apexi gains. Now I know this might just have been a fluke in gains but from Jeff's link above it clearly shows the apexi is a better dirt trapping filter and thats the most important thing in my eyes. Gains if there are any just a bonus. Matt

 

Maybe the Apexi has a better resonance-reducing design or better internal velocity stack? Did the K&N have a velocity stack?


Dave

 

the filter that came with my berk did not have a velocity stack, i got a lil nervous about the blown maf thing and went to a cheap APC filter( you get what you pay for) it sucked, so i decided to put the K&N back on and yeah i noticed a lil difference.. also about the APC filter, i went to blow it out with the compressor and couldnt even feel the air comming out of it!!!

Neal728 RR-3003 is the K&N with the velocity stack in it, i dont remember the number for the on that came with my berk intake.

http://www.ajusa.com/cgi-bin/knfilte...rt_num=RR-3003

 

Thanks for the info. I think for 50 bucks for the K&N that needs replacing every 12k or so, or the Apexi that needs replacing every 30k for 110 bucks, I'll go with the Apexi when I replace my K&N, which is in about 4k.

 

Huh? K&N air filters don't need replacing. You clean, reoil and reinstall.

 

just be carefull about reoiling it

 

No it didn't. It wasn't the normal cone shaped K&N that everyone has. It was Berk Technologies that is the same size at the bottom as the top.

 

Just reveived my intake order from FirmFabrication and notice that the filter is manufactured by Vibrant Performance.

http://www.stylincompacts.com/parts....rtfamilyid/647

They Vibrant performanace filter also have a similar Funnel Ram Filter like the Apexi filter and is warranty for 100,000 miles.

You guys should try this brand out!

 

Has anyone installed the Apexi on the Injen yet. I know you "say it will fit" but has anyone actually done it

 

I will be installing it on my Injen as soon as I get it. Hopefully by Monday.

 

With just a circular 3" inlet sucking air, there will be turbulance. I think that is why when you take off the filter, you don't gain that much or don't gain at all. With the apexi, there is a funnel to smooth out the air flow into the 3"inlet, allowing more flow.

To those of you with a JWT or Stillen and have access to a dyno, try to dyno your car with just a 3" inlet tube and no filter, then again with a velocity stack attached with no filter, there might be a difference.

Personally, I would buy the apexi. 1) In theory, there should be gains...+/- 1hp? 2) It has the best filtration according to the test on the web site. 3) Everytime I pick up a car magazine in japanese, guess what filter I see in front of turbos on R34s, RX7s, etc. most of the time...the apexi.


The apexi needs an adaptor to fit any car. All you need is that adaptor and a coupler. That should attach to the end of your injen piping, replacing you KN.

 

Does anyone know if any other car line has experienced blown MAFs like our Maximas? Are our MAF's unbelieveably cheap? None of this makes sense.

 

I thought I remembered reading that the 00-01 MAFs were of better quality. A few other things I've seen...

1) people switching from K&N to Apexi on the Frankencar setup have had MAF failures...

2) buying a 00-01 MAF as the replacement is a possible solution...

What I haven't found is the price for a replacement, or if it's still under warranty, I assume we can just throw back on the stock airbox and everything and limp our way back to the dealer, yeah?

I do like the long time BTW changes of the Apexi, and the good reports from some .org members, but the MAF failure scares me.

 

so unless the apexi somehow flows more air than no filter at all (ie FI), then a filter really is just a filter and those who bought the $100 apexi just got ripped.

 

Yeah I would like to know too. Does the 2002-2003 Altimas or 350Z's have this problem???

 

AMEN
