K&n or bmc?

[goker]

After I took the K&N off there was NO DIFFERENCE in the DYNO pull! In fact in my other Carrera, an '02, we completely removed the stock air filter, put the air box back together and did another dyno pull, no difference. We all said, "Hummmmmm....I guess K&N's don't do much."

Let me see if I get this straight, are you saying you compared two runs; one with K&N filter and one with "no" filter and you got the same results? Just curious.

I can vouch for this. I use a K&N filter on my car and had one on my last bike. Ive NEVER had ANY problems with them, and you can't expect to rejet your bike or get full use out of your exhaust without something like it. I have the recharge kit for K&N filters and it lasts a very long time. Stock filters may have smaller mesh, but with the oil on aftermarket filters it does just as good of a job if not better all the while allowing you to unlock your engines potential.

On a side not, a K&N filter may void your warranty. I know this is true for some car manufactures but have no idea about Yamaha. If a vehicle has a "dry" stock filter and you switch to an oil based, any issues related to the intake will not be covered under warranty. Just something to think about & possibly look in to.

If you go to the K&N site you will find a lot of interesting info regarding warranty issues. Also some of the arenas they don't warranty their filters are off road and racing! Go figure! Here's a blurb copied from one of their web pages.......It's interesting and they do have independent laboratory tests to back their claims. Not to say that that's even the truth but....?
Then again, what is a pledge? Is a pledge legally binding?

Okay everyone hold up your right hand....

K&N Consumer Protection Pledge


We want to make sure that when you buy a K&N Lifetime Air Filter or Air Intake System, you can be confident your vehicle's warranty will not be impacted. We also want you to feel confident that even if you experience a difficult dealership, we will step-in and resolve the issue, so you won't have to. Therefore, we make the following Pledge:

K&N pledges to our customers that they will not be taken advantage of and charged for a repair due to a dealership warranty denial blamed on the presence of a K&N product.
Steven Rogers, CEO

Consumers buy aftermarket products for many reasons; higher quality, added performance, visual appeal, work requirements or just as a way to be different. The Car Companies do not like aftermarket products and never have. They believe consumers should only buy their parts. There is a battle going on for your freedom of choice and that freedom is being threatened by a number of wolves dressed in sheep’s clothing. Be it in the name of emissions standards, public safety, warranty requirements, or dependence on foreign oil, all these worthy causes may be used as a reason to reduce your right to choose and force you to buy only O/E Parts. That’s why on virtually every aftermarket company's web site; you will see a reference to the Magnuson-Moss Warranty Act, a law needed to protect your right to buy non-O/E parts. There has even been a bill introduced recently in Congress called the “Right to Repair Act,” a bill designed to protect your right to have your vehicle serviced by an independent repair facility.

A frustrating problem we occasionally face is service technicians making false or unsubstantiated claims about aftermarket products, even something as standard as a K&N air filter going in the factory air box. These false allegations may then used as a reason to deny a legitimate warranty claim and force a consumer to pay money when they should not. We are horrified that the presence of aftermarket products could in rare instances be used as an excuse for taking advantage of a consumer. In all instances we have experienced so far, the dealership’s position is mere speculation unsupported by any evidence. However, the dealership is in the “power position” and more often than not, they will win this unfair fight with a consumer, who needs their vehicle back. We are going to balance the scales a bit. We will use our resources to make the consumer whole and challenge the dealership. See warranty page for details.

Binding or not, It's great to see a company publicly standing behind what they do. It's an old fashioned concept that your word is your bond. Let's hope that this starts a new trend in other consumer organizations.
I have a K&N filter as that wad what was available at the time I purchased it.
