Does anyone have a good alternative for the stock filters for the 2003 CL55, I had 2 K&N ordered but reading the forums scared me offof keeping them.

I have used K&N for about 2 years now, keep them oiled, all is well. That said, if anyone knows why these BMC filters are better I might consider upgrading. Thanks,

that is what everyone keeps telling me to stay away from the K&N because of the oil, they say it will mess up something, but you have used them for 2 years, any problem with them, I have them on my Acura NSX and really like them.

No, I have had no problems, and I have actually not had to oil them again, I just checked to make sure they looked good. I put em on in September 2007. The only difference I noticed on intake was you can hear some kind of blow-off (like a Subaru STi redlining the 1-2 shift) if you tip the throttle pretty hard from a slow speed, particularly if you have it in comfort mode (215 model). It is one of those things where I dont THINK it was making that noise from before I made the changeout, but I didn't have the car that long before switching so I may have just not noticed. Sorry this does not help with the CL65 issue.

For
50 bucks a set use oem filters.They out flow k/n.Let far less dust through,and
no worries about oil.
Autohausaz.com has them for both 55's and 65's
K/N and green are snake oil
$200 for what ever brand mentioned is a pool of snake oil

I think the only difference I mentioned was a change in the sound. Even if there is a 10HP gain to the rear wheels on a V12TT, what would that be about 2%? You gain and lose more than 2% depending on the level of your gas tank. However, if you want to shave a % or two off your ET, then more power to you, (assuming TMC M5's data is correct and there is an increase in HP)

True, you can "gain" a weight savings and improve your power-to-weight ratio by having less fuel (gasoline weighs approximately 6lbs per gallon). But that argument is moot because you will be getting the benefit of both when you run at the track (unless you like carrying extra weight for no reason). So in effect that 2% rwhp increase is seen in conjunction with a 2% weight savings. This only further improves the performance of the car.

Can members be banned for sheer stupidity? If so, the bell is chiming "sound8," a member who has annoyed nearly all who have encountered his childlike posts which achieve nothing other than giving readers a bad impression of the English.
Now, on topic, I've been impressed by airflow charts posted after BMC fitment. I've also heard good things about K&N, though some complain about their oily-ness. The gains from either one are small, but small gains are what it's all about at the drags.

Secondly, we are talking REAR WHEEL HORSEPOWER not the manufacturer's figure at the flywheel, which you quoted.
I am sorry to break this to you, but you have no knowledge of the V12 TT platform. There aren't very many options out there for performance intake upgrades. The only option until recently is a RENNtech air box which they charge $5,600 for and claim an additional 15hp at the crank...you would have thought by your comments that I was advocating that purchase...
![crazy](https://mbworld.org/forums/images/smilies/crazy.gif)
No that isn't my dyno run...the person who did it bit the bullet to see if an air filter made any difference in performance. He was tired of people using their butt-dyno as the determinate of whether a performance mod works or not.
If you would look a little closer at the dynos you would notice that the run with OEM filters was done in slightly lower humidity and ever so slightly better barometric pressure. When you correct these dynos to SAE, the aftermarket filter run is corrected upward 1.2% and the run with OEM filter is corrected upwards 1.1%. So peak SAE corrected is 528.51rwhp for aftermarket filter vs 518.60rwhp. Thank you for pointing out both a further advantage (albeit small) of the aftermarket filter...and your lack of knowledge.

I only mentioned performance gains in comparison to the weight of the gas to illustrate how small 2% is. Of course the 2% would not suddenly disappear when you boosted performance further by say removing the spare tire, draining fuel, getting lighter wheels to lower rotational inertia, etc. Yes, obviously it all adds up, and based on those dyno results, if I were eking out every less tenth of a second, I'd throw on the aftermarket filters, despite what looks like a hit to low end torque.

Also, you will notice that we are looking at runs 6 and 8 in a span of 17 minutes. Changing the filters is a 5-10 minute activity because you need to unscrew a number of bolts on each airbox. There was also apparently a run #7 in between. So the car probably wasn't totally cooled down. That could be causing the minor "hit to low end torque".

Sounds reasonable Tom. I thought the data looked a bit off there. Bottom line, it looks like these things work, although people have apprehensions about the oil. On a personal level, I wish we had some 55 data to go alongside that 65 data.

If there was any measurable reduction in low end tq you would be literally talking about 1-2lbs ft. Every little increase in HP bit adds up and filters are just part of the equation, and in my opinion 10HP was more then I had expected. I dyno each and every modification on my car so I can see the before and after gains as most of my mods were "experimental" When I did this filter mod no filters were comercially available for the V12tt. I measured them myself and modified a universal KN filter to fit. I also had an exhaust system hand fabricated which have the car another 14+hp to the wheels and 37hp under the curve. There is/was no full exhaust system available for the V12tt's I also was the first to add a larger reservoir to my trunk, with ice netted me another 15+ rwhp. The most I have dynoed is 555rwhp, but I have done a couple of other things since then that should put me close to 570rwhp currently. So in the grand scheme of HP, that 10HP is a major part of the overall equation.
