Max Capacity Posted June 5, 2012 Share Posted June 5, 2012 Yep they are different. I got mine for like $80.00 from Car Quest auto parts, other places had prices all of the place and some said it would take 2 weeks. Car Quest had it for me for lunch time. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
