Going to be replacing my Air Filters in my 06S, Autohauz has some regular filters and Heavy Duty ones. Which ones should I get? Appears the "Heavy Duty" have some sort of pre-filter installed.

I would not get anything "heavier" that the stock, light like K & N maybe

The Heavy duty are OEM filters just have the extra pre filter. Mann Filter

The "heavy duty" filters were intended for desert areas: Option code I1L2 "Equipment for countries with dust-laden air". I wouldn't use it if you don't need it.

Does seem like it may be more restrictive.

I live in Bahrain and my '06 CTT has the I1L2 Option code, does that include any thing with regards for "Equipment for counties with dust-laden air" was wondering about the Cabin Filter also being heavy duty?
Thank you,

I recently changed my air filters. The ones I took out looked like regular filters the ones I put in had a thin foam over the filters. Not sure if it was the filters or maybe loose clamps I tightened up but afterwards I had better throttle response. The filters were not advertised as heavy duty, they there the factory replacement
