K&N AIR FILTER P/N

[THC1]

Hello: I have a 21 Laramie crew 2500 gasser.......I can't seem to find a part number for a K&N filter anywhere. Even sent an email to the manufacturer from their website and they blew me off.

Anybody know what it is? Would the diesel filter be the same size?

Yes the diesel filter should be the same size as the Hemi filter on the 2019+ trucks

that said... why? Stock filter flows good, K&N oiled filter will add negligible benefits. The oil has been shown to cause issues with the MAF sensor on some vehicles too.

K&N have really sold people with their marketing on a product that doesn’t do ****.

Thanks........I've used a K&N in every vehicle I've owned with no issues. I really don't expect benefits other than I never have to purchase another filter.

funny thing about K&N is if people run them and do oil analysis they usually have more silica/solids in the oil because until a K&N gets really dirty they do not filter all that great.
