Designed to permanently resolve oil intrusion into the spark plug wells—a common issue with OEM plastic tubes—these CNC-machined aluminum replacements deliver unmatched durability, perfect fitment, and long-term reliability.\u003c\/p\u003e\n\u003cp\u003eEach tube is machined from solid 6061-T6 aluminum and anodized for corrosion resistance.
