The caliper sliding bolts are one of the most overlooked wear items in your braking system. Subjected to constant motion and often without adequate lubrication the guide bolts see a lot of wear and tear. Factory BMW caliper guide bolts are very expensive from the dealer - these 304 stainless steel bolts are less than half the price and provide outstanding resistance to corrosion and wear. They are manufacturered with tighter tolerances than the factory bolts too.

Price is per bolt unless noted (2 required per caliper).

The perfect upgrade for the connection between your thermostat and cylinder head. Designed with durable silicone and billet aluminum to greatly outlast the OE rubber-and-plastic combination.

Some of the weakest points in BMW cooling systems can be the OE plastic fittings, which break down from constant temperature changes, softening these components. When this happens, even simply moving the hose slightly could cause the fitting to crack, causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but also stand up to the wear and tear of a daily driver.

Features:

Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance.

Much stronger part than OEM plastic

Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and reinstallation.

Constructed of 4-ply reinforced silicone for improved durability over the failure-prone OE rubber hose. Fluorosilicone-lined internal layer for exceptional chemical resistance. Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability. Follows OEM form for perfect fitment. Utilizes OEM O-ring 11537545278 to ensure a proper seal. Replaces Genuine BMW Part Number: 11537584549
