Expert Answers about Pontiac GTO

• Recommendation for an Oil Filter Adapter for Installing an Oil Cooler on a 2006 Pontiac GTO
• The low profile sandwich adapter, item # D25771, is 1 inch thick. If you know the thread pattern on your engine oil filter the 13/16-16 threads may work but a universal kit is what we normally recommend, so you have the correct adapter for your application. This kit is the Low-Profile Sandwich Adapter - Multiple Engine Filter Threads, item # D25783. I would not recommend using a shorter oil filter with less capacity than the OEM oil filter. It sounds like you want to install an oil cooler...
