obvious answer! but what about pollen filters etc?
1 question asked
Pollen filter (Activated Charcoal Type) can not filter all exhaust smell, so replacing it won't fix the actual problem.
What engine is in your car?
Usual problems / smells are oil smells... due to oil leaking from the Valve Cover Gasket & the Chain Tensioner Gasket, that then drips onto
the exhaust manifolds & catalytic converter.... the smell then makes its way into the car via the fresh air intake / pollen filter.
Exhaust flex pipes are common leak areas.
