i was reading in a magazine that a lot of cars have air filters for the passenger compartment up in the cowl area or under the dash. do the bonnevilles have them ?? i havent looked yet. just curious if they have them and if so where they are located.

I think that only the 2000+ models have them.

I just changed the one in mine.
It cost $50 Cdn and the recommended change-out is every 20,000 km.
Mine was plugged up with pollen dust.
