Oil filter for Acura Honda Isuzu
The Baldwin Filters B1425 is a spin-on oil filter built for Acura, Honda and Isuzu passenger cars and light-duty trucks. It uses an M20 x 1.50 thread and a 9.8 micron rating to trap contaminants before they reach the engine. The cartridge includes a 20 psid bypass valve and an anti-drainback valve for immediate pressure at start-up. Transparent housing lets a technician confirm media condition without removal.
Sustained filtration under pressure
During extended service intervals the 9.8 micron media maintains flow while holding fine particles that accelerate bearing wear. The 20 psid bypass valve opens only when restriction exceeds the set point, preventing oil starvation during cold starts or heavy load. Anti-drainback silicone retains a prime so lubrication is instant on every ignition cycle. Media area and structural pleats resist collapse under continuous pump pressure.
Replaces shorter-service spin-on filters
Install this filter when the maintenance schedule calls for a 9.8 micron spin-on with M20 x 1.50 threads and the included bypass and anti-drainback features. It upgrades from basic filters that lack a bypass valve or use a coarser micron rating. The jump is worth it for engines that see frequent short trips, towing or dusty environments where finer filtration extends oil life. Not suited for applications requiring a different thread pitch, a larger canister diameter or a non-spin-on mounting style.

Questions about this item
How much oil pressure does the 20 psid bypass valve allow before it opens during extended runs?
The built-in bypass valve opens at 20 psid, letting oil flow even if the filter element becomes heavily loaded during long operating periods.
Which thread size must the engine block have for the B1425 to seal correctly?
The filter uses an M20 × 1.50 thread, so the mounting pad on the engine must match that exact pitch and diameter.
Will the anti-drainback valve on the B1425 protect older Honda and Acura engines from dry starts?
Yes, the integrated anti-drainback valve holds oil in the filter after shutdown, reducing wear on older Honda, Acura and Isuzu engines at the next cold start.
