I have a 1998 Maxima SE, and it's an automatic. I'm looking to give it a few extra horsepower and a "throatier" or more "raspy" sound without spending all the money on an exhaust system. Would a cone filter increase my horsepower enough to make a noticeable difference in my acceleration, and would it make the car sound any different?

 

You will see gains in the upper RPM range, but your low end power will suffer, you'll actually have less power down low than with the stock airbox. So since you have an automatic, I wouldn't recommend the cone filter, the best thing for you would be to get a real CAI.

 

To compensate for the low end "loss" with a cone filter, get a hybrid intake instead.

Cone filter with a CAI upper piece.

 

ya just buy the cone w/adapater and upper portion on ebay for ~$100....or just buy the cone and adapter and make the upper portion yourself for $15...search around for it

 

I agree... I have an auto and this setup works perfectly for me...

I have the filter and adapter. Can anyone tell where to find the piping that I need to modify it?

 

E-bay... E-mail DOHCCIVIC that sells the K&N Cone Filter w/Piping. He will sell you the upper pipe for about $50 shipped. Or, you can order a more expensive one from any company that makes CAI for Maxima's...

 

Do you really think there is a low-end loss? Because my G-Teched 0-60MpH times only improved with a HAI, and both tests were under the exact same conditions.

Excuse me mr. moderator sir, but how does the upper cai piece counter the low end loss of the cone intake? Theory works for all gens? BTW. I just did this exact mod last week. But it's because Dirksmooth needed a stock intake and I didn't have a spare.

 

hey, i like how you have your intake looks.
i already have a stillen air filter but i'm interesting in getting the upper part.

what is that called? , where can i buy it?,
i tryied searching on ebay but can't find it.


i would really appreciate your inputs.

hey good luck with your max,
it looks good.

thanks,

Thanks for the props. You can buy it through DOHCCIVIC on E-bay. Just tell him you want the upper piping. He charged me $50 shipped.

Good Luck, and thanks again.

 

Want so really noticeable mods without increasing the noise of the engine. Buy a protorque higher stall convertor and then buy some 205/50-15 tires on lightweight 15in rims. BTW get a shift kit at the minumin a trans go, if you can afford Don's VB get that instead. The TC + tires will give you more lowend punch.

 

I think a reason why the upper cai piece is better than the stock setup is that it uses hard pipe. Being completely smooth will incease the velocity of the air. There's that one "accordian" section of the stock intake system after the MAF sensor and those ridges create turbulance.

I work with industrial vacuum web cleaning systems. "Web" meaning just one continous sheet coming from a roll. I spec hard ductwork for these vacuum systems whenever possible. I avoid flexible pipe with ridges because it creates turbulance which decreases the performance. If I use more that 8' of flexible ductwork i have to increase the size of the blower motor. In a manufacturing facility 8' of ductwork is a drop in the bucket.

When I made the switch from CAI to hybrid I lost no low end.

 

i currently have the stillen pop charger.
and am thinking about adding the upper pipe to mines.


is that what you have now?

That's what he's refering to. Hybrid intakes are typically a JWT Pop Charger, or Stillen Cone Filter with the Upper Piping in place of the intake resonator.

ok.
i'm getting myself one too.
i waiting for a reply from ebay to buy just the upper piping like you did.

ps. can you really feel the difference with this mod.

The butt dyno enjoys it. I don't know how much real world performance gains you get with it, but I've noticed better low-end power. Typically with Pop Chargers, you get great high-end power, but the low-end suffers. The upper piping helped out considerably in counteracting the low-end loss.

 

i emailed that guy from ebay.

but some of his reviews on ebay say that he doesn't responds his emails.


how did you pay him when you bought it from him?

 

Paypal, and no, he doesn't respond by E-mail very well...
It kinda sucked waiting.

 

you have his telephone # ?

 

I just got an email back from the ebay guy and he said they are putting the upper piece up on ebay tonight. He told me $49.99 + shipping. I am getting one for sure

 

yea man, me too.

let's try this one.

 

does $50 include clamps and the silicon adaptors that connect the pipes?

 

good question.

i'm going to find out.
i'll post it as soon as i find out.

i'm getting it regardless.

 

It includes all of the blue adapters/clamps, except for a 3/8" plug for Automatic owners... Instead, it includes a blue tube to connect to your manual transmission cooler.

i got it.

i finally got and installed that upper pipe.
i could hear the air socking in...
it doesn't really sound too loud unless you floor it; i like how it feels. it also, made some improvement on my low end power.


my next mod will be to add the rear strut bar.

 

I'm trying to decide which hybrid intake to go with.

The K&N Cone Filter kit w/ piping vs. the CAI/Stillen...

Any opinions on which setup results in more HP gain? pros, cons of both?

 

honestly, i would go with the CAI/Stillen.
i just figured it was much easier for me to just add the cone filter.
but after 5 or 6 months i then added that upper pipe to my cone filter

the way i feel it ; its as if i had the best of both worlds.
i have the stillen cone filter and the additional UPPER PIPE.

Wait a minute...Isn't the Stillin Intake just a K&N filter with adapter? Meaning its the same as the K&N Filter Kit + adapter?

 

Maybe its the shorter length of the tube.

 

this is the stillen hi flow intake.
and then i added the upper pipe.

on the other hand there is what it's called the CAI/Stillen.
which is that long pipe.

i don't have a picture of the CAI but maybe you could search for it.

 

Don't buy "Stealin" stuff... The JWT Pop Charger was copied by Stillen anyway... When you buy Stillen you're only buying the name...

 

Thanks for the info. I think I'm going to go with the K&N Intake with piping...

 

i agree with you.

 

Coming from a Popcharger to a Cattman CAI, I can tell you the Cold air intake OWNS. I can't really notice the difference in mods, but as soon as I went from stock box --> pop charger I could notice right off the bat the lag with every bum bum bum sound the intake makes. With the CAI, I can spin my tires more off the line and my the intake spools up faster. Also, the sound that the CAI makes under WOT absolutely blows the pop away.

Cyrus, maybe they were the same becuase when you tested it, it was winter time? And where you live it's soo cold that the intake makes little difference. But summertime in Florida it makes every bit of difference.

 

hey,
i did my setup just like you did.
with the pop charger and the upper pipe.
i love it so much.

ps. 'the hose that connects from the upper pipe to the engine bay'; i think we should be concerned about oil being sucked into the throle body.
when i was doing the setup i noticed some oil on the tip of the engine where you would connect the air hose that goes to the upper pipe.


any opinios

None of them own the Frankencar Intake and thats my word. I showed one of my coworkers how it sounds and he was blown away. I stand buy Steves product in every way.

 

Just try a CAI dana and your mind will be changed...CAI's sound is unique from a pop or hybrid becuase it resonates in the fenderwell and throughout the tubing...I'm sure you've heard one before? Amazing plssed off dragon sound under WOT, yet the most docile of the intakes in traffic.

 

Where to get more info about this? CAI dana?

 

Deezo, would you care to reiterate?
