This kit provides two machined aluminum brackets and a 36\" extension harness that retain the factory M10 knock sensors but relocate them to a much more serviceable position on the lower block edge. It’s a practical upgrade for engine builders, tuners, and anyone who wants to simplify future sensor replacement or diagnostics.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit simplify knock sensor access?\u003c\/h3\u003e\n\u003cp\u003eBy moving the sensors from the valley pan area to the outside edge of the block, the CNRAQR brackets eliminate the need to remove the intake for routine sensor service. The relocation harness extends the factory sensor lead by 36 inches so the OEM connectors reach comfortably at the new mounting points.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUses original M10-thread Gen 3 knock sensors—no new sensors required.\u003c\/li\u003e\n  \u003cli\u003e36\" harness provides ample length for routing and connector reach.\u003c\/li\u003e\n  \u003cli\u003eAluminum brackets mount to the block edge for improved access.\u003c\/li\u003e\n  \u003cli\u003eReduces labor time when replacing or diagnosing knock sensors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my GM LS engine model?\u003c\/h3\u003e\n\u003cp\u003eThe kit is made specifically for Gen 3 knock sensors and fits a range of LS Gen 3 RPO engines, including LS1, LS6, LQ9, LM7, L59, LR4 and L33.
