What kind of spark plugs do a big block use?
Also if your running Nitrous, I always run NGK’s. plugs do alot of things. iron, to platinum to iridium.. I had all three in one engine. a little engine, but gas math is gas math.. an engine is an engine. big block is probably still quite happy with big iron plugs…the oldest design of all. :
What kind of wire does a spark plug use?
These performance 8mm spark plug wires exhibit only 600 ohms per foot of resistance, with high noise-suppression capabilities. Features include red wires with white Chevrolet insignia and black boots. Manufactured with double-wall silicone construction.
What kind of spark plug is best for high horsepower engine?
High horsepower engines and especially supercharged, nitrous, and turbocharged powerplants making four-digit horsepower are increasingly susceptible to pre-ignition. For tuning these engines, it’s best to start with a very cold plug with a short ground electrode. Ground electrode length is not a function of heat range.
Why are spark plugs not supposed to be anti seize?
Spark plug companies don’t recommend anti-seize on threads because it lowers the torque required to install the plug. Torquing the plugs to the published spec with anti-seize overtorques the plug which potentially could break the internal seal between the insulator and the shell, creating a leak path.
Can a gapped spark plug be indexed?
Indexing plugs can only be achieved when a conventional-type “gapped” plug is the threaded into the head. Merely throwing in a set of plugs, without aligning the gap can cause the grounding strap to shield the electrode.
Where do I put the spark plug in my car?
Second, simply install the plug into the head and discern the direction the reference mark points, ideally, you want the gap to face the intake valve if this engine features a standard fuel injected or carbureted setup. This may require multiple attempts with different plugs to achieve the end result.
What happens if you put in spark plugs without grounding strap?
Merely throwing in a set of plugs, without aligning the gap can cause the grounding strap to shield the electrode. This, in turn, will require the air/fuel mixture to travel farther to be properly ignited by the plug, this kind of impedance can affect timing and result in an incomplete burn.
How can I get more control over my spark plugs?
Another way to solve this dilemma is to utilize a set of copper indexing washers, that will give you control more control over the plugs position thanks to their varying thicknesses. Notice how the gap side of the plug is directed to the intake valve?
