FAQs
Q1: Will this fit my BS6 / J-series engine?
A1: Not unless the engine’s filler cap dimensions and threading match exactly. This cap is intended for UCE platforms as per RE’s listings.
Q2: Is installation difficult?
A2: No — RE lists it as a ~5 minute job. Remove stock cap, attach new cap with seal, ensure the inlay is aligned.
Q3: Does the branded inlay rotate / misalign?
A3: No — the inlay is installed last so the logo always sits correctly when tightened.
Q4: Does using this void warranty?
A4: No — as a genuine RE accessory, when used correctly it should not void warranty on the engine or parts.
Q5: Does it leak or compromise seal pressure?
A5: No — it uses OEM threading and sealing geometry; ensure gasket/washer is clean & properly torqued.
