Description
The Mishimoto Oil Cooler Service Pack (MMRP-OC) is a purpose-built maintenance kit that puts everything you need to reseal a sandwich plate back in one box. Rather than hunting down individual seals from a hardware store, this pack bundles the exact components Mishimoto engineers specify for a proper reinstall, so you can get your oil cooler system buttoned up correctly the first time.
Servicing an oil cooler shouldn’t mean chasing down mismatched seals or guessing at sizes. This Mishimoto cooling service pack simplifies that process by combining the most commonly needed sandwich plate seals into a single, ready-to-install kit. It’s designed to help maintain a proper, leak-free seal and reliable performance every time a sandwich plate is removed and reinstalled during oil cooler kit maintenance, cutting down on both parts-sourcing hassle and vehicle downtime.
Vehicle Applications
This is a universal service pack intended for use with most Mishimoto oil cooler kits that utilize a sandwich plate design. Because fitment is tied to the sandwich plate style rather than a specific make or model, it’s compatible across the range of Mishimoto oil cooler kits that share this design. It is important to note that this kit is not compatible with systems that do not use a sandwich plate, systems with unique sandwich plate designs, BMW-style fittings, or the Mishimoto MMOP-TPS.
