I have found Marc to be very knowledgeable when it comes to the ZR-1, he changed my injectors some time back and car has ran great. He recommends Bosch oil filter and have used them ever since with no problems.

I've cut open many different flavors of filters from my old RX-7 to see how they are constructed. (I know it's not a Z but the filters are cheaper and I don't mind using it as a guinnea pig) K&N is one of the best filters money can buy, hands down. But it's pricey. Wix is my filter of choice for every vehicle I own, because of the construction/build quality and the number of pleats inside (bang for the buck here.) I get mine from Amsoil when I buy a case of 10w40 for my Z.

I agree oil Filtration is obviously a number one concern with any oil filter but the main reason for our talk about the oil filters on the LT5 is which one has the best anti-drain backvalve to help prevent timing chain rattle on some LT5's at startup because of the inverted oil filter design.... The older BOSH oil filters I experience Zero chain rattle but the newer Bosh filters still part number 3401 I get timing chain rattle. I still have a few of the old design with the Orange colored anti-drain backvalve and it works perfect. I have experimented with the new design were the anti-drain backvalve is black and It rattles ever start up. It's like flipping a light switch with the difference..20220123_134735.jpg

Any late 2023 oil filter recommendations? Was about to order a couple from Rock Auto.
