I have an '02 Trans Am WS6. It has a pretty healthy LS1, puting out about 450 RWHP. Redline is 7,100. What filter would you recommend on this engine? It currently has Ravenol 5W-30 in it with a K&N HP-1007 filter. Stick with the K&N? Is something like a Wix Endurance too restrictive? Would the Purolator Boss be a good compromise? Of the filters below, I have listed both the short and long versions. Ground clearance is a concern on this car. I do like that the Microgard has a bypass valve, should it ever need to flow more than what the media might allow. I'm just thinking "out loud" here. What are your thoughts?
