Mishimoto 2008-2009 Pontiac G8 Performance Aluminum Radiator

If you're looking to give the V8 in your 2008 or 2009 Pontiac G8 some extra breathing room, this Mishimoto Performance Aluminum Radiator is a solid upgrade. It's built to handle the demands of everyday driving, spirited runs on back roads, or even a day out on the track, ensuring your engine stays cool when it matters most.

This radiator swaps out the factory's thin core and plastic tanks for a much more robust setup. It features a thick, 2.2-inch, two-row aluminum core that offers a 39-percent increase in core volume over the stock unit. The entire thing is fully TIG-welded, including the end tanks, which means you get a strong, durable piece that's built to last. This improved cooling capacity is exactly what a powerful 6.0L V8 needs to perform at its best without overheating.

Installation is designed to be straightforward, replacing your original radiator directly. It's suitable for both manual and automatic transmission G8 models. Plus, it comes with Mishimoto's Lifetime Warranty, so you can install it with confidence knowing it's backed for the long haul.
