New Honda 20HP

[lawnMaster5000]

I just had to purchase a new honda 20HP (GXV 620) b/c my old one quit.

- on the old engine (GXV 620 w/ 300 hours) they dealer claims that i was running low oil and didnt take care of the filter. Well i would argue with both of those, but whatever. They said i should be running the engine with over full oil (thought that was bad) and that my filter was too old, pretty new, but cant argue with the fact dirt was getting through)

What i am wondering though, is should i purchase an aftermarket air filter and the amsoil oil filter system for the new engine. Both of these things would be cheaper than another new engine. but would they really benifit me at all. and if so where is a good place to get aftermarket air filters.

PS honda just redesigned the filter b/c it was a poor design and air was getting past filter element. (could this qualify me for warantee claim?)

thanks for any help
