    KN filter for V

    Does anyone know if there is a KN filter available for the V? I need to breathe!!

    I checked KN's website and they only show an oilflter for the V...

    Will the regular CTS filter work? Perhaps another car's filter?

    Thanks.

    I don't know enough, but unless it uses the same airbox as a regular CTS I doubt the filter will be the same Time to fashion your own cold-air intake

    I've been told by Doug Rippie Motorsports, well known LS1/LS6 tuners, that products are coming from the suppliers but still probably 30 days off.

    Isn't that the sport model CRV from Honda?

    If you get a K&N, be sure to remove it before you bring it in for service on a check engine light.

    For this reason, I would not use an aftermarket air charger system in my CTS. It not worth having engine problems and voiding your warranty.

    Yeah, I guess I'd ask why bother with it at all?

    Aside from the religious wars over whether K&N filters filter adequately even when clean, the K&N filters have maybe 1/4 the total filter surface area (count the pleats) of an OE paper filter, which means it's going to plug up a lot faster than the paper filter would. What good is a 'free-flow' air filter if after 5000mi it's more restrictive than a 25Kmi OE paper filter?

    And the more often you clean it, the greater the possibility of your over-oiling the thing and contaminating the MAF...

    I witnessed someone get a 1 wheel HP improvement (248 to 249) on a Dynojet Saturday (car was a moderately-tweaked '92 SHO) swapping from a clean OE filter to a clean K&N.

    Again I'm have held fast that I have YET to see ANY conclusive SCIENTIFIC evidence that they DO filter adquately (esp. compared to stock). This should be of primary importance OVER performance increase. I just recently obtained the name of the Dir. of R&D @ K&N and wish to hear (from the horses mouth) his opinion of the evidence that I have (obtained at my own cost) - I will be contacting him directly when time allows.

    This makes me ask what would the Dyno show if there was NO air filter in place during the run.

    Use at your own risk.

    Agree... I have heard of the problems, and always replaced rather than cleaned the K&N filters.

    If you only switch the air filter, there is little power to be gained. Some of the aftermarket air intakes combined with the filter add a few HP. Many people claim they can feel the difference, and their engine revs easier. Whatever.

    I am not against an entire intake solution, but would always replace the filter rather than have warranty issues with re-oiling.

    ...but even a new K&N filter is supposed to be oiled, and it still doesn't have nearly as much surface area as a paper filter.

    I think it's what we call a typo. I'll rely on you to do all of my proof reading in the future.

    Keep in mind also that GM is aware of the excess oil residue from aftermarket filters, and has advised dealers to check both for the presence of these filter installations, but also oil residue on the sensors that would not be there with the OEM filter. They are watching this on the CTS and the CTSV.

    Re: KN filter for V

    On vehicles equipped with MAF (mass air flow) sensors if the oil residue were to gather on the tiny wire that is in the MAF it could effect operation. The vehicles PCM (powertrain controll module) measures how much air is entering the engine thru a process of heating the tiny wire inside the MAF it measures how much voltage it takes to heat the wire to a specific temp and the more voltage it take is equal to the amount of air rushing past this wire. If it takes more volts to heat to wire then more air is going thru the engine. At idle it takes less voltage and therefore knows there is less airflow.

    The oil will insuate the wire and need more voltage to warm it up.

    It also will coke up the throttle plates and make idle problems. In vehicles that have fly by wire throttles ( no throttle cable) the motor must overcome the sticking plates then you end up with either a surgeing idle or erratic response when initally takeing off from a stand still.
    This is also why its important to change your oil regularly
