This is a great deal for the Purolator PL14610 PureONE Oil Filter. List price is $15+ but on sale at Amazon for $5 each. It applies to 4th and 5th Gens Maximas and I30s. This is similar to Mobil M1-110. The PL14610 is @ 0.6" longer than PL14612. It's really up to you if you want to use this filter on other generations. I have used M1-108/110 interchangeable in the M35 w/o any problem. You have to order 5 (max) to qualify for free shipping.

EDIT: Please make sure it fits your car. BTW, you can buy PL14610/14612 at Advance Auto for $5 + tax.
