Note: 2007-2012 applications require the removal of the aluminum tab on grid heater.
Upgrade your engine’s reliability and eliminate a known failure point with this OE Grid Heater Hardware Upgrade Kit. Engineered for durability, safety, and peak performance.
This innovative solution removes the two problematic factory nuts found in the stock grid heater and replaces them with a secure, direct connection to the lower busbar. The result? Full heat output is maintained, so you keep the cold-start performance you rely on without the risk.
Why Upgrade Your Grid Heater Connection?
The factory grid heater design routes up to 200 amps of electrical current through a small bolt and nut inside the intake. Over time, this connection can loosen, corrode, or fail, leading to dangerous arcing. In worst-case scenarios, the nut can break free and fall into the engine, causing catastrophic damage to pistons, valves, and cylinder heads.
Built for Performance & Peace of Mind
- Eliminates Failure-Prone Hardware – Removes internal nuts and bolts that commonly fail
- Direct Busbar Connection – Ensures a stronger, more reliable electrical path
- Self-Locking Threads – Integrated into the lower busbar to prevent loosening over time
- Maintains Full Heating Function – Keeps your stock grid heater operating at full capacity
- Prevents Engine Damage – Reduces the risk of loose components entering the combustion chamber
The Smart, Preventative Upgrade
Don’t wait for a costly failure. This kit is designed to fix the root flaw in the OE electrical connection while preserving factory functionality. Whether you rely on your truck for daily driving, towing, or heavy-duty work, this upgrade delivers long-term reliability and confidence under the hood.
Protect your engine. Improve your connection. Drive with confidence.
