Slightly off topic, maybe tt can help they did not recommend fitting the likes of itg,k&n as they are oil based and it can sucked into the engine and cause problems to the tune of £300, I said fit anyway so they did. any thoughts ?
....EEK!!
- I thought that my ITG Pro panel filter wasn't oiled! They certainly instruct NOT to oil it.
Trouble is, not oiling an air filter which is designed to be oiled dramatically reduces the effectiveness of the filter. The dust and crap is meant to "stick" to the oil, and you periodically remove the filter, wash it in specific solvent, re-oil it, and refit it. If it aint oiled, then your engine is digesting a lot of unnecessary crap, especially if you live near a beach, or in a dusty area.

I think the dry "cotton" types are supposed to be the best compromise between improvement over standard paper filters, and performance increases.
Usual disclaimer applies though - ETTO.
