The TRP-1046 Spark Plug Indexing Tool is perfect for builders who want to ensure proper spark plug clearance without wasting time threading plugs in and out of the engine. Instead of checking each plug one by one, this tool makes the process fast, accurate, and frustration-free. Once you identify eight plugs that align correctly for your cylinder heads, simply thread them into the corresponding holes on the TRP-1046 Spark Plug Indexing Tool and mark the underside. The next time you buy new plugs, just thread each one into the tool and match your original marks — no more guessing, and no more checking them one by one in the engine. The TRP-1046 Spark Plug Indexing Tool is manufactured from aluminum and black anodized for both looks and durability. In addition to making replacing your next set of spark plugs a breeze, this tool will also double as a safe way to store a complete set of plugs. Works with both gasket (flat seat) and tapered seat spark plugs. Fast Shipping, Always. We keep our tools in stock and ready to go, shipping most orders the same day or the next business day. If something is listed as out of stock, it will be replenished and ready to ship within about 2 weeks.
