Hi & welcome to LOC.
Maintenance for the air filter on the induction kit is not that often, just follow instructions once every few months i.e. give it a clean, dead easy.
I have a number of Prolex parts & no complaints at all, all good kit & excellent service from Dave.
Once the induction kit is on it does expose the engine, best thing is some cleaner & elbow grease to make it sparkle. Quite a few of the guys in here have painted some of the plastic covers, Aztebandit1 has a good photo on his profile of his red detailed engine bay.
