Oiwa Garage Tech Note
"This is the Asami Engineering racing filter for the Acty. A good anti-drainback valve holds oil in the filter overnight, which is why the top end quiets faster on the next cold start."
Frequently Asked Questions
How do I know when this oil filter is due?
You cannot test a filter directly, so go by the oil change. If the oil on the dipstick is dark and gritty, or the filter has been on for more than one change, fit a fresh one with the oil.
Should I pre-fill the filter before fitting?
On this sideways mount you cannot fully fill it, but oil the gasket and part-fill what you can so the engine sees pressure sooner on the first start.
Can a cheap filter hurt this engine?
A filter with a weak anti-drainback valve lets oil drain back overnight, so the top end rattles on cold starts. A decent filter is cheap insurance.
