Vehicle Fitment

• 1988-1991 Honda Civic, 1.5L L4, Fuel Injected

Fitment Notes

• Retailer listings show a wider year range (1987-1995) and additional models (Civic II/III/IV, CRX I/II, Honda Shuttle) than K&N's official confirmed application (1988-1991 Civic/CRX, 1.5L F/I) - the broader listings likely reflect international chassis designations or generic templated copy; confirm your specific model year and engine before ordering
• Sources also show a discrepancy in outside filter dimensions (some list outside length as 8.625 in., others as 6.625 in.) - verify physical dimensions against your factory filter before purchase

Product Description

The K&N 33-2025 is a washable, reusable panel air filter designed as a direct drop-in replacement for the factory filter on 1988-1991 Honda Civic and CRX models equipped with the 1.5L fuel-injected engine. Built from layered, oiled cotton gauze, it's engineered to improve airflow while maintaining strong filtration performance.

As a reusable filter, the 33-2025 is designed to last the life of the vehicle rather than requiring periodic replacement, needing only a cleaning roughly every 50,000 miles. It's backed by K&N's No-Hassle Lifetime Limited Warranty, making it a cost-effective long-term alternative to disposable OE filters.

Given some variation in retailer-reported year ranges and physical dimensions for this part number, Civic and CRX owners - particularly those with vehicles outside the 1988-1991 range - should confirm exact fitment against their factory filter dimensions before ordering.
