About this product
BOSCH Cap (1 420 521 001) is manufactured to OEM tolerances, ensuring a direct-fit replacement that restores your vehicle to factory specification without any modification. This part supersedes original equipment references: 00 03 002 149, 01301111, 08 70 168 500, 0870168500 and 14 more. Matching these numbers confirms a like-for-like replacement with no loss of function. BOSCH is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
