Do they make a K and N air filter for a 1500? If so how does it affect the milage and performance?

I have one but didn't notice fuel economy increase or power increase. I like the longer maintenance interval before taking the tank off.

For a 1500 what? If your referring to a Valkyrie, the answer is yes. It may have little impact on mpg. If the condition of the existing filter is poor, the new filter probably will increase mpg. |

So, you think after 12-24 months, the K & N oil is still wet and doing it's job? I think the OE is good for two years of most ordinary riding. The K &N can last a lifetime with maintenance, the OE does not. But I think the OE has a longer maintenance interval (replace) than the K & N (clean and re-oil). |

I believe the OEM recommends replacement at 15,000 miles. The K&N recommends cleaning and re-oiling at 40,000 miles. How it improves or degrades mileage and performance depends a little on how good you are at applying the correct amount of oil. |

I was unaware of the K & N 40K interval recommendation.
Who would wait 40K????
I've run K & N in cars, trucks and bikes. After a year, they are dry as dust (and I think a lot of dust is going thru them).

I was going to replace my air filter this spring, and found that she had a K&N. After 40K miles (3 years) from purchase (yeah, I know, way late but I had the tank off to do de-smog and Dan-marc install) the filter was still wet, and filthy. I cleaned and re-oiled it and put it back in. Runs fine (though I'm replacing the filtered Dan-marc with non filtered as soon as it comes in; starvation issues).

If you're finding it dry and dusty you're not properly following the oiling directions. Actually, if you're treating once a year and I'm treating at 40,000 miles, we're really not all that far apart.  |

Different spin on the same question....do you leave the K&N sponge in or out?
I currently have it in, but was wondering for those who have it out if there is any issues or better performance?

Mine is out. I think most leave them out, I'm not really sure why though. |

I left mine out due to it becoming brittle and crumbling into little pieces.  |

I think the best way to achieve better mpgs is to control the 'throttle temptation' (i.e. resist the urge to make those 6 cylinders to scream).
My I/S has had variations of fuel consumption between 27mpg to 40mpg (yeah, I'm talking about highway!!) depending on the way I rode it.

The stock Valk application for KN is to leave it in. Once the oil in the filter is dried out (like a year), I think you want it for added filtration of dirt. Some bikes may be a bit lean w/o it.
Most leave it out, not I.

I currently have the K&N and have new OEM filters ordered. I am going back to OEM to compare the mpg. The last time I had the tank off to clean the K & N and oil it I found that it was dry and there a slight dirt film in the airbox. Not sold on the K&N at this time for this reason.

Mine is out. I think most leave them out, I'm not really sure why though. the reason I left mine out was because after installing the gas tank, fuel line, vent line, petcock vacuum hose, chrome neck cover, tank bib and seat, I turned around and there it was! Right where I'd hung it to dry.........and it's still there.  |

A K&N had been installed in my Valk by a PO. Glad to see it since I have used them in nearly all my previous bikes. Mine gets cleaned and oiled every winter, long before any published service interval, so the inside of the air box has always been fairly clean. The foam pre-filter is in place, not on a wall. Since I don't know anything else, I can't judge power or mpg differences. But, at the RPMs we run at, less than half the maximum volume demand of engine, I can't imagine the filter would make much of a difference, as long as they were clean.

I've had a K&N in MGM for over 230K+ with the filter in, for maybe 170K+ miles.
It got brittle and started to disintegrate at around 170K.
I pulled it out, called K&N, told them what happened, they sent me a new one.
I had MGM back together, and said self, put that in at next reoil.
Self, forgot about it till I read this post.
I image it is probably rotten again and ready to disintegrate, if it hasn't already.

RJ mine are in the cabinet I never installed them. They seem to flow better without them in there.
