Our take on the Red Line 90226 Big Twin 20w50 Power Pack Oil Package with K&N High Performance Oil Filter (Complete Kit, Black Filter)

This is a bundled oil change kit for Harley-Davidson Big Twin motorcycles: Red Line's 20W-50 full-synthetic engine oil plus a K&N high-performance oil filter. Red Line is an ester-based synthetic known for staying stable under high heat, which matters on air-cooled V-twins that run hot in traffic. The K&N filter has a hex nut on the end for easier removal and a 1-inch nut that takes a standard wrench. It suits riders with Evolution, Twin-Cam or Milwaukee-Eight engines who want one box for the engine side of a service; 2007-up 96-inch and larger Twin-Cams still need an extra bottle of primary chain case oil.

Questions and answers

Does this kit cover a full Harley Big Twin service?
No. It covers engine oil and the oil filter only. Primary chain case and transmission fluid are separate.
Will it fit a 2007-up Twin-Cam 96-inch or larger?
Yes for the engine oil and filter, but those engines need one extra bottle of primary chain case oil to reach their capacity.
What grade is the oil?
20W-50, the grade Harley-Davidson specifies for most Big Twin engines.
Why use an ester-based synthetic?
Ester synthetics resist thermal breakdown better than conventional oils, which helps air-cooled engines that run hot.
Is the filter reusable?
No. The K&N is a disposable cartridge filter with a nut on the end for easier removal.
Does it work on Milwaukee-Eight engines?
Yes. Red Line lists the kit for Evolution, Twin-Cam and Milwaukee-Eight Big Twins.
