i took my car (2k max se) to this guy who is the head mechanic at nissan, and he told me that the intake i put, nothing big, i forgot where i got it from, its basically a k&n filter on the tip of the original intake with some other things, like a metal piece to hold the intake in place
anyway, he says that the intake is actually HARMFUL and DECREASES the speed of the car, too much air let into the engine will damage the pistons? is this guy for real??

 

How can air be damaging to the piston? Make no sense! If you're force-inducing the engine w/air, by mean of supercharger/turbo system, then perhaps that will wear out the internal engine components faster.
With an aftermarket air intake, it will NOT be "harmful" to the engine but may killed the MAF sensor quicker? As for decreasing in performance, it really depends on your the intake's setup, whether it's a HAI/CAI, temperature conditions, condition of sensors, etc...

 

An intake will not hurt your car.

 

I put on a Weapon R Intake about 3 months ago and well it ran great, until last week. I stalled the car at a light and when I started it back up and began to drive it would rev past 2500 rpm's. So I took the intake off and put back on the stock intake and well now it runs great. No problems at all. I still want an intake on the maxima but not a Weapon R or at least the Dragon Foam Filter. So can I still use the Weapon R pipe and put on a K&N filter? If so does anyone know the size of the K&N filter to use with the Weapon R Pipe?

 

Yea, I don't recommend Weapon R filters to anybody.

 

Can I use the Weapon R Pipe along with the MAF Adapter and just put a K&N filter on it? Do you know what size K&N Filter would fit on it? The piping is 3" with 3" reducers!

 

i have one. i blew my maf at first but nissan replaced it free of charge. i threw the WR dragon intake back on the same day i got the car back and all has ben good for the last 3K+ miles. and it sounds nice. I had a 96 200sx Se-R and a 95 maxima SE before this one and all i use are Weapon r intakes.
the dyno on the WR web page says 7.2 hp gain at the wheels. that's impressive for any intake, let alone a WAI.

can't blame the intake for the mafs blowing though, that's nissans fault.

 

hct67 you can use that weapon r pipe and maf adaptor you just need to get the measurements off the old filter cone and see which k&n filter is resembles iot the most

 

Thanks, Appreciate the assistance and help. I just want an intake back on the Max as I can't stand driving around so quietly. With an intake theres that awsome growl and I miss it alot!!! Plus I miss the feel of it or at least I believe theres a HP gain with the Intake. Anyways, thanks alot for your help!!!

 

This shows why we shouldn't that our Maxima's to Nissian dealer mechanics!!!

 

I've heard mixed opinions about K&N filters letting stuff through. I believe as long as you oil them & keep them pink there shouldn't be any problems. I run K&N filters (oil often) in all my cars and have yet to have any mechanical problems(Knock on wood)

the mechanic is supposedly hookin me up on the flushing of the engine, transmission, and changing the o2 sensors. hes also changing out the rotors and brake pads. hes doin all for i think $500. but he said that he recommends to put back the original intake to extend the life of my car.
oh and i think a couple of my wheels have dents, and hes swapping those out... i mean the guy seems like hes tryin to help...maybe i heard him wrong...does the aftermarket intakes put wear and tear on anything?
thanks for your responses everyone

 

No...well, the good ones don't. He's probably not nearly knowledgeable enough to make an overall assumption that all intakes are bad for all engines...
