Critical Impact of Quality Air Filter on Engine Service Life
- Unfiltered sand and grit enter the combustion chamber, causing cylinder wall scuffing and piston ring wear, with a full engine overhaul costing $1,500–$2,200 for Rezzo / Tacuma models.
- An incorrect air-fuel ratio due to clogged filters increases fuel consumption by 12%–18%, raising daily operating costs for car owners and fleet operators.
- Contaminated intake air damages the mass air flow (MAF) sensor, causing rough idle, power loss and failed emissions inspections.
