Spark Plug Gap

The proper spark plug gap for your 1998 Ford Ranger 2.5L with 8 plugs depends on the specific spark plugs you're using. Here are some recommended gap values:

Champion RC8PCY: Gap of 0.8mm.
NGK PFR6B-II: Gap of 1.1mm.

I really needs checking against the spark plugs you have chosen? .045" is about right for most.

Look under the hood for a sticker of some sort, maybe by the core support or try looking in your owners manual.

Mr Bobby I manage to find in my books few things about your model on spark plugs. I hope will help you. Depends the make you have the Gap: 1. Autolite Ap606 Platinum Gap 0.60, 2. AC DELCO Professional Platinum Gap 0.60, 3. NGK G-Power Platinum TR55-1GP Gap 0.60, 4. CHAMPION RS12 PLP6 Gap 0.60, 5. CHAMPION COPPER PLUS RS13LYC5 Gap 0.60, 6. Platinum Alloy Gap 1,1mm if your engine size is 3.1,also for 3.1 3ngine DENSO TT PLATINUM Gap 0.04 inch. select and carry on .

The plug gap is .040

It is normal for the electrodes to wear as the plugs age. This increases the distance between the electrodes which in turn leads to a gradual increase in the firing voltage required to jump the gap. The gap on a standard spark plug grows about 0.00063 to 0.000126 inch for every 1,000 miles of normal driving, which means the firing voltage requirements creep up about 500 volts for every 10,000 to 15,000 miles of driving.

The OE Champion plug gap specifications are .048 - .053" or 1.24 - 1.37mm. in accessing and changing the plugs on the PT. They have the same gap specifications as the OE plugs. Most owners gap at .050. We prefer to use the Champion Double Platinum plugs, which are more durable, provide extended plug life, and reduce the need for maintenance, given the difficulty However, if you experienced excessive rough idle with your last set of plugs we suggest gaping the OE and DP plugs to .042 and consider replacing the OE plug ignition wires.

Excessive gap can cause performance and drive ability problems, including hard starting, an engine miss and or hesitation under load, and can shorten the life of the plug (accelerated tip erosion). If it were me I would re-gap them to the correct specs if they are currently gaped at .060.
