This reproduction of a vintage Special Tuning accessory is perfect for road or race cars that are used during cold weather. For road cars, you may want to use this product to "blanket" the cooler when the weather is chilly to allow the oil to remain in the optimal working temperature range. For race cars, on those cool morning track sessions, this is ideal to block the cooler to speed warmup. It simply snaps onto your oil cooler, but you may want to add a supplemental restraint for high-speed track use to prevent loss.
