Tip & How-To about GMC Blazer
Most cars now days have plugs that last 100,000 miles however they do need to be changed sooner due to the electrode stretching and the gap increasing thus causing a miss or poor performance, Spark plug manufactures sell all types of replacement plugs this is to save you money by telling you what I recommend on plugs.There are many plugs on the market called split fire plugs and their prices range from $4.00 each up to $14.00 each however these plugs do no better than the recommended plugs from the manufacture, with one exception Platinum plugs last longer. However never buy the expensive plugs unless you are burning oil and if you live in a state that you have to have emmison tag to get a new tag for your plates your wasting your time and money to install these expensive plugs. So always buy the plugs from the manufacture and do not buy after market plugs. Also when changing Plugs change the wires or you will damage the plug wires when you change the spark plugs. So replace the wires. Do to the high voltage on the newer cars use dielectric grease on each end of the new wire coat the inners boot of the plug wire so that there is no voltage leak between the wire and engine block, a dirty plug will cause leakage and make the car run rough and miss and could damage the engine. Put the dielectric grease on both ends and make sure it does not touch the tip of the plug or the tip of the coil it is connected to.
