Sinister Diesel has reinvented the Exhaust Gas Recirculation (EGR) cooler with this great new model with the same fit as your factory EGR cooler. Our less-restrictive design reduces clogging by replacing the narrow thin walled inner tubes with high-flow stainless steel tubing for improved reliability and durability. Manufactured with high-quality TIG welds, each EGR cooler is pressure tested and is guaranteed to protect against leakage.
ARP head studs are cold-forged for molecular uniformity and then heat treated for strength before machining for a clamp load rating of 220,000 psi. Far superior to the holding power of factory head bolts, ARP head studs are cheap insurance against fretting and failure of the seal between your engine block and cylinder head that can result in severe engine damage. Each set of ARP studs includes matched nut and hardened washer hardware for even distribution of clamping force and accurate torque readings during assembly.
The head gaskets included with the Sinister Diesel Heads Up kits are Grade C head gaskets from Mahle Motorsport which are 1.05mm thick to compensate for any material removed during required cylinder head resurfacing. Every Mahle head gasket is manufactured to OEM quality standards from stamped multi-layered spring steal with beading around each combustion chamber to increase overall sealing pressure and micro-polymer seals around the oil and water passages to ensure leak-free performance against any imperfections in the head or block surfaces.
Each kit also includes a full complement of required gaskets for every engine additional engine component that seals against the cylinder head including gaskets for the exhaust manifold, up pipe, upper and lower valve cover, along with valve cover grommets, valve seals, and turbo drain seals.
