Oil Filter Sandwich Plates

Billet Oil Filter Sandwich Plate Create a convenient pressure-side oil supply connection for a bypass oil filter system with an Insane Diesel billet oil filter sandwich plate. This optional upgrade can reduce installation labor by approximately 2–3 hours, depending on the vehicle and application. Each sandwich plate is precision-machined from T6 billet aluminum, finished with a durable black anodized coating, and custom engraved with the Insane Diesel logo. Why Choose an Insane Diesel Sandwich Plate? Dual-seal design: Combines a precision-machined aluminum-to-aluminum sealing surface with an O-ring seal instead of relying solely on an O-ring. T6 billet aluminum: Provides strength, durability, and precise fitment. Black anodized finish: Helps protect the aluminum and provides a clean, professional appearance. Custom Insane Diesel engraving: Identifies the plate as a genuine Insane Diesel component. Time-saving pressure-port access: May reduce installation labor by approximately 2–3 hours, depending on the vehicle. Available Sizes 3 1/16" × 1 1/8": 3-inch sealing surface; weighs 7.6 oz 3 3/4" × 1 1/8": 3 1/2-inch sealing surface; weighs 9.5 oz Compatibility and Fitment Select the sandwich plate that matches the oil filter sealing surface required for your application. Each plate can fit more than one vehicle or engine when paired with the correct stainless steel oil filter thread extension. A compatible Oil Filter Thread Extension is required and sold separately. Choose the correct thread size for the engine’s oil filter housing and the selected sandwich plate. Plate dimensions or thread size alone do not guarantee vehicle compatibility. For verified engine-specific fitment, choose one of our Complete Oil Filter Sandwich Adapters, which includes a correctly matched sandwich plate and thread extension. Important Installation Instructions Replace the sandwich plate O-ring whenever the billet oil filter sandwich plate is removed. Thoroughly clean the oil filter thread extension and mating threads before installation. Apply Blue Loctite 242 or an equivalent medium-strength threadlocker. Torque the oil filter thread extension to 35 ft-lbs. Check the thread extension torque every time the engine oil filter is changed. Important: This product includes the billet oil filter sandwich plate only. Oil filter thread extensions are available separately and are not included. Warning: Incorrect fitment, improper installation, or insufficient torque may allow the thread extension or sandwich plate assembly to loosen. Confirm compatibility, installation, and final torque before operating the engine.
