The dealer wanted $34 for new air filter, new KN panel filter is $40. i just have a question... did anyone have any issues with KN filter or oil from it? especialy since car is drive by wire not throttle cable?

i had 2000 maxima and those cars had MAF sensor issues from KN filters(due to the oil) it would blow the sensor, i went through 2 at $90 each! and if you dont oil the filter, lots of small particles/dust gets into the manifold/engine. Thanx.

 

I had a fitment issue with my Comptech Icebox lid but not with the filter, the oil, or its performance. With the stock airbox you should be fine.

 

I've had a K&N drop in filter for about 1,700 miles now.
not a single problem.

 

no issue at all! go for it!

 

Ran one for over a year sans the resonator box and then added the Comptech lid. In adding the Comptech Icebox, had to do the weatherstrip modification and all is well.

 

That is one of the issues with nissans that my mechanics complain about all the time. They say that the MAF sensor is kind of built into the intake manifold on hondas so that issue doesn't occur. Does anyone know if there is any truth to this?

 

I guess you are referring to the oil in the filter coating the MAF sensor... I can tell you, with the TSX, it isn't an issue that we have seen at all.

 

As long as you follow the recharging directions and not drench the filter with oil then there won't be a problem.

 

Should there really be a concern about sucking in small amounts of unfiltered air? Or did you add sealing material just to reduce intake noise?


I just dropped a K&N into my Icebox over the weekend and I absolutely love it. I wasn't expecting much of an improvement, but I realize now that I had been suffocating my engine by sticking with the standard CT foam filter. My car is pulling noticeably harder now (especially in the lower RPMs) and throttle response has improved. I've also had the added benefit of finally being able to hear my supercharger whine in-cabin. It now almost sounds like an airplane taking off at WOT, and by adding weatherstripping I'm afraid I'd lose that sound altogether which is something I'm not willing to do.

For anyone running a Comptech Icebox + S/C, I HIGHLY recommend using a drop-in K&N filter.

 

Yeah, there is an issue. Micro-particulate will be mixing with fuel and become burned in the combustion chamber, if it doesn't attach itself to the valves first. It needs to be sealed up and allow the filter to do its job.

 

i've had mine in the icebox for about 4k miles and no problems. as mentioned by others, i also used the weatherseal to hopefully keep the box air-tight b/c of the fitment issues.

i should probably clean it soon.

 

well put it in, as expected no diff on the butt dyno. only concern is that overtime small particles will get into manifold and the valves, like that article with the test of various air filters... its true KN and other high flow filters allow for better breathing but at the expense of later damage. after all thats how it breathes better. if you hold a KN up to the light you can actually see the holes. ehh i guess if no one heres had any problems its ok.

 

How often do you guys clean your filters? Do you prefer the spray on or squeezable kit?

 

I'm not sure "damage" is a good word to use. I've not seen anyone prove that a K&N contributes to damage of anything except for some inline sensors and that has more to do with over oiling the filter media.

 

1x per year and I have the spray kit. It works well.
