Anyone ever had valvetrain noise with Supertech?

7317 isn't an e-core and there's some other one that isn't an e-core, probably the size that's equivalent to a Nissan "shorty" filter. I don't remember the part # off hand though.

Pretty much all of the Asian car STs are non-ecore: 7317, 6607, 3593, 3682, 9688..etc

The American STs like 3614, 16, 3600, 2, 3506, 10060, etc... ARE ecore.
