Please note that we use a general description for the engine "type/style" to help make it easy for you to find parts. However, not all engine manufacturers have the same specs which can prove to be an issue when finding replacement parts. To solve this issue and ensure our parts fit across many models Outside Distributing designs and packs our parts to work with the majority of the units on the market.
