OxyGenie M12.1-1.5 x 15mm Oversize Piggyback Oil Drain Plug – Stainless Steel Self-Tapping Repair Kit

OxyGenie presents the Oversize Piggyback Oil Drain Plug, crafted from premium stainless steel 304 with CNC precision. This two-piece design re-threads the oil pan hole, helping to establish a secure fit and a reliable working seal. It’s built to fit the original drain plug’s footprint while offering an oversized piggyback option that can simplify maintenance without replacing the entire oil pan.

In real use, the plug’s rugged construction and exacting manufacturing translate to confident handling during routine oil changes. The kit is designed to minimize downtime and make maintenance more straightforward, especially when thread wear or damage makes a standard drain plug unreliable. While results can vary by vehicle and condition, many users appreciate the potential for a durable, leak-conscious seal and a more streamlined repair process.

What you get

• 1x stainless steel self-tapping oversize piggyback oil drain plug (M12.1-1.5 x 15mm)
• 1x L-shaped hex key for installation and removal
• 2x fluorine o-rings for main plug sealing
• 2x red copper gaskets for piggyback seal

Key benefits and how it can help

• High-grade stainless steel 304 provides hardness and durability for repeated use.
• CNC precision helps ensure a snug, repeatable fit that aligns with the original drain port.
• Oversize piggyback design offers an alternative to full oil pan replacement when threads are compromised.
• Designed to deliver a consistent seal, reducing the chance of oil seepage during drainage.

Installation is described in simple steps: clean the oil pan area, thread the main plug in with a few forward and backward turns, remove, clean any debris, then tighten to about 14 ft-lbf, followed by attaching the piggyback plug. For removal, hold the main bolt stationary with a wrench when loosening the piggyback component.

Why choose this repair approach?
