Questions about this item
What thread size must the engine block have for the B141 spin-on filter to seal correctly?
The filter uses an M20 x 1.5mm thread, so the engine block must provide the matching M20 x 1.50 pitch for a proper seal.
Will the 20 psid bypass valve still protect an older engine if the filter element becomes clogged?
Yes, the built-in 20 psid bypass valve opens at that pressure differential, allowing oil to circulate even when the 23 micron element is restricted.
How can I confirm the anti-drainback valve is functioning after installation?
After the engine has sat overnight, start it and watch for immediate oil pressure; the anti-drainback valve keeps the 3-7/8" canister full so pressure builds without delay.
