Spark Plug Replacement & Ignition Service

Is your engine hesitant to start or feeling sluggish on the road? At 786 Repairs, we provide expert spark plug replacement services to restore your vehicle’s power and fuel efficiency. Over time, spark plugs build up carbon deposits or wear down, leading to misfires and poor performance. Our technicians use high-quality iridium or platinum plugs to ensure your engine fires perfectly every single time, protecting your ignition system from unnecessary strain.

Small components make a massive difference. Fresh spark plugs don’t just help your car start; they optimize the entire combustion process, saving you money at the pump and preventing expensive damage to your catalytic converter.

Step by Step in Spark Plug Service

We don’t just “pull and plug.” We ensure the entire ignition sequence is healthy.

Diagnostic & Coil Check

We inspect your ignition coils and boots for cracks or electrical leaks before removing the old plugs. This ensures the new plugs perform at 100% capacity.

Precision Installation

Old plugs are removed and analyzed for signs of engine health. New plugs are gapped precisely to your manufacturer's specs and torqued to prevent cylinder head damage.

Performance Testing

We finish with a computerized idle check to confirm smooth firing across all cylinders. You'll feel the difference in throttle response immediately.
