Key Features:

  • 2-Row Brazed Aluminum Core: Large, efficient core design provides optimal coolant temperatures and proven 15°F temperature reduction

  • Increased Capacity: Holds an additional 0.64 liters of coolant compared to stock radiator
  • Mishimoto 1.3 Bar High-Pressure Radiator Cap: Raises coolant boiling point for safer, more efficient cooling system operation
  • Magnetic Oil Drain Plug (M12 x 1.5): Captures metal fragments to keep your coolant system clean
  • Premium Construction: High-quality aluminum construction resists thermal stress and fatigue from constant temperature cycling

Whether you're making hard pulls on the highway or cruising mountain roads, this performance radiator delivers reliable cooling when you need it most.

The fellas at Autoplicity where great, very proffesional, and great price as well. I will definately be using them again. ohh, and super fast shipping... thank autoplicity...

Easy process

Smile:)

So far, they did good getting my package to me...downfall it was opened from whoever was subcontracted to send it to me. however they promptly have provided me with a return slip and we will see where it goes from there. they were quick to help fix their problem as long as i had pictures of what was wrong. still cheaper than anywhere else.

Autoplicity was quick and easy. Painless web format. Shiped right away. And reasonably priced too.

Shipping seems a bit high even with the discount

First time buyer

Autoplicity had the best price and was easy to order and use. My items were shipped promptly!

After a almost 2 month backorder through Summit... y'all had what I needed in stock and shipped same day! Which was delivered in 3 days! Awesome!
