RYANSTAR Carbon Fiber-Style B-Series Cover
RYANSTAR describes this cover as compatible with B-series engines, including Civic B16 and B18 applications. Its listed features specify a plastic carbon-fiber-style construction. The product information says the plastic style is lighter and better at isolating noise than metal. It also describes a sealing function intended to help prevent lubricant leaks.
Best for: Buyers who prefer a lightweight, carbon-fiber-style appearance over a metal cover. It was selected as a distinct material and style option among the listed B-series covers. Confirm exact engine and mounting compatibility before ordering, since detailed vehicle fitment is not provided in the listed features.
Consideration: This is described as plastic, not carbon fiber. Choose an aluminum option if metal construction is a priority.

Buying Guide: How To Choose A B-Series Spark Plug Cover
Does the cover fit your exact engine and vehicle?
Start with engine code and vehicle year, model, and trim. The X AUTOHAUX listings provide named applications, while the Modengzhe products use a broader “VTEC B-Series if applicable” description. RYANSTAR names B16 and B18 compatibility but does not provide a detailed vehicle list in the supplied features. When fitment is unclear, compare the cover and mounting points with your current setup before purchase.
Should you choose plastic or aluminum?
The RYANSTAR option is described as plastic with a carbon-fiber-style appearance and noise-isolating properties. The other covers are aluminum alloy or 6061 billet aluminum. Choose based on your material preference and the product’s stated features; the information provided does not establish that one material is universally better for every build.
Which finish and dimensions matter?
Choose silver or matte silver for a lighter appearance, or black and matte black for a darker look. Modengzhe states dimensions for both finishes, so those measurements can help with a preliminary comparison. Dimensions alone do not confirm fitment; mounting position and engine configuration also matter.
What should you check before installation?
Review the product’s installation notes and confirm what hardware or instructions are included. X AUTOHAUX says instructions are not included and recommends professional installation. Its listing specifies screw installation at the original car hole position. Do not assume that installation details from one product apply to another.
