To change the spark plugs on a Vauxhall Zafira open the hood of the vehicle. The spark plugs will be located on the engine. It is best to used a spark plug removed to unscrew the plugs. They will be connected to a cable. Remove the cable. Replace the plugs with new ones and reattach the cable.
.035 inch........for the ABSOLUTE best power use Autolite AT3 spark plugs. I had 65 327/365hp in 65. Motor Trend did a test on spark plugs using a 389 cu in GTO engine. They gained ten (10) HP by simple change the plugs to Autolite AT3. Good luck.
You may bolts on left side cover to access spark plug.The plugs are located on the bottom sides of the engine.
You have to use platinum-tipped spark plugs ONLY.
NGK laser iridium spark plugs.
the best spark plugs for all ford vehicles are the motorcraft type, which they come from ford.
The best spark plugs are the original equipment plugs that were installed by the manufacturer at the factory. Sometimes you may need to go to a dealer to get the exact plugs.
don't have my manuel how many spark plugs are there in a 1997 cutlass supreme oldsmobile. need to change them all v6 engine. what is the best brand to buy thank you
The front spark plugs are easy. To change the rear plugs the top mixing (plenum) chamber has to be removed. This involves removal of cables, electrical connectors, throttle body, vacuum hoses, & rear support brackets. Nasty job. Best left to a professional.
You can do this on your own if you have any knowledge of cars. If not, a mechanic is the best way to go.
