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.

Just picked up a 94 and it has an STP filter on it now. I have 2 Bosch filters ready for when my wife finds out I bought the car.......she does not kniwcyet.......SO in my house. Once I break the news Mobil 1 synthetic oil and the Bosch filter.

Re: Which oil filter do you use?
 

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.

Re: Which oil filter do you use?
 

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..Attachment 17127
