The mountune Billet Oil Filler Cap is reassuringly over-engineered to provide both visual improvements to your engine bay and reassuring function, every time you top up your oil.

Machined from T-6061 aluminium, a deep laser-etched 52 centre-lock wheel design adds an aesthetic boost, whilst complementing the range of mountune under-bonnet upgrades.

Functionally, the internally-sprung mechanism in the cap provides a positive 'click' in use, so you'll always know when it's fully tightened.

Features:

• Direct replacement for OE part
• Billet aluminium with Shadow black anodised finish
• 52 centre-lock design
