• Engine code: many parts here are matched to a specific engine, such as SR20DET, RB25DET/RB26DETT, 2JZ-GTE, 13B-REW, 4G63, G16E-GTS or Subaru EJ. Confirm your engine code before ordering.
• Chassis code: check your chassis code, for example S14/S15, GD/GG, B8/B8.5, C7, R53, Mk7/Mk7.5 or G80/G82. The same model name can cover several different chassis.
• Thread size: drain plugs and magnetic bolts are listed by thread (M12, M14x1.5, M22). Match the thread on your sump or fitting.
• Belt length: APR supercharger belts come in several lengths (1270mm, 1300mm, 1320mm). Select the length that suits your pulley setup.
• Bore size: ring compressors are sized to the bore. The ARP unit listed here suits an 86.5mm bore.

Installation by a professional is recommended. Some items, such as balance shafts, oil gallery restrictors and secondary air system delete kits, involve work inside or on the engine. Others, such as weld-on MAF flanges, need fabrication. Tools in this collection, like the crank pulley, supercharger pulley and fuel pump removal tools, are designed to make specific service jobs easier on the listed vehicles. Before removing or blocking off an emissions-related system, check the road rules that apply to your vehicle.

What counts as an engine accessory?
These are supporting parts and tools that work around the engine rather than core internals. Examples include belts, block-off plates, drain plugs, brackets, spacers, sensor flanges and model-specific service tools.

Which oil drain plug size do I need?
Match the thread size of your sump. LEYO magnetic drain plugs are available in M12 and M22, and the Spoon Sports magnetic bolt set is M14x1.5.

Which APR supercharger belt length suits my Audi?
APR belts for the S4/S5 (B8), A7 (C7) and A8 (D4) come in 1270mm, 1300mm and 1320mm. The correct length depends on your pulley setup, so contact us if you are unsure.

Should I install these parts myself?
Installation by a professional is recommended, especially for internal engine parts, delete kits and weld-on components.
