The RX8 twist oil cap from AUTOEXE replaces the factory plastic filler cap with a machined aluminium unit finished in red anodising. It gives the Series 2 engine bay a deliberate, coordinated look. That matters at a point you touch every time you check the oil.

It is a direct-fit part for 2009-2012 Mazda RX8 models. No modification is required to install. For any rotary owner who takes pride in what’s under the bonnet, swapping the standard cap is one of the simplest ways to sharpen engine-bay presentation.

AUTOEXE RX8 Twist Oil Cap Features

  • Machined aluminium construction gives the cap a solid, premium feel at every oil check. It is noticeably more substantial than the standard plastic item.
  • The red anodised finish is hard-wearing. It resists the heat and minor splashes typical of an engine bay, keeping its colour longer than painted alternatives.
  • A quality twist oil cap delivers secure, tool-free removal with positive engagement. Routine top-ups feel more satisfying than with the OEM plastic cap.
  • Series 2-specific fitment is engineered for Mazda RX8 models built between 2009 and 2012. It drops straight on without adapters.
  • Finally, the red finish pairs naturally with other AUTOEXE engine-bay details, making this a natural starting point for a coordinated bay build.

For RX8 enthusiasts who open the bonnet regularly, fitting a quality RX8 twist oil cap turns a functional item into a considered detail. The machined finish and anodised red colour hold up to genuine use, not just display. The twist action also feels noticeably more positive than the OEM plastic it replaces.

Round out the engine-bay presentation with the AUTOEXE Brake Fluid Cap, which carries the same brand aesthetic across another visible service point. For a meaningful engine-bay upgrade alongside it, the GREDDY TRUST Oil Filter is a direct Series 2 fit and a high-quality piece at a frequently serviced location.

Frequently Asked Questions

Which RX8 models does this AUTOEXE oil filler cap fit?

This AUTOEXE twist-type oil filler cap is specified for Series 2 Mazda RX8 models built from 2009 to 2012. It is not confirmed for Series 1 RX8s, so check your build year before ordering.

What material is the AUTOEXE RX8 oil filler cap made from?

The cap is machined aluminium with a red anodised finish. Anodising gives it durability against handling and minor chemical contact, while the machined surface provides a deliberate mechanical appearance at a regularly accessed service point.

Is this a direct replacement for the stock oil filler cap?

Yes. The AUTOEXE twist-type cap is a direct replacement for the Series 2 oil filler point and maintains the same compact form, so the surrounding engine-bay layout is unchanged.

What does twist-type mean for this oil cap?

Twist-type refers to the standard rotational fitting method used at the filler point. The machined aluminium grip gives it a more tactile feel compared to the smooth plastic OEM cap during routine oil checks.

Does fitting this cap offer any performance benefit?

This cap is a presentation and tactile upgrade, not a performance modification. It updates a visible, frequently handled detail with a quality machined finish and a red anodised colour that can coordinate with other engine-bay accents.

Will the red finish hold up to engine bay heat and oil contact?

Anodised aluminium is generally resistant to the heat, moisture and minor oil exposure typical of an engine bay environment. The anodised coating is part of the metal surface rather than a paint layer applied on top.

Is there a version of this cap for Series 1 RX8 models?

This listing is specified for Series 2 RX8s built from 2009 to 2012. If you own a Series 1 RX8, check the RX8 Upgrades catalogue for the correct Series 1 variant before purchasing.
