Seeking Advice on Spark Plug Gap for Ford 302
I’m currently working on tuning up my Ford 302 engine, and I’m a bit confused about the correct spark plug gap settings. I’ve heard various recommendations, but I want to get the best advice from fellow car enthusiasts who know this engine inside and out.
Key Factors to Consider
- Ignition System: I’m aware that the gap can vary depending on whether the engine is running points or has an electronic ignition system. Has anyone here made adjustments based on this factor?
- Engine Variants & Year: There are different variations of the 302 engine (like the ones from classic Mustangs and Fords). I’m specifically looking for recommendations based on certain years or models. Does the gap change significantly across those variants?
- Modifications: I’m curious about how modifications (like performance intake, exhaust systems, or any tuning done) might affect the optimal spark plug gap. If you’ve modified your engine, did you alter the gap from the manufacturer’s recommendation?
Previous Recommendations
I’ve heard anywhere from 0.032" to 0.045" for various setups, but I’m looking for more personal experiences, especially if you’ve tested different gaps and noticed a difference in performance.
Conclusion
If you’ve had any experience with this and can share what worked best for you, I’d greatly appreciate it. Understanding the spark plug gap for the 302 is crucial for optimal performance, and I’m keen to hear everyone’s thoughts!
Thanks in advance for your help!

The recommended spark plug gap for a Ford 302 is typically around 0.030 to 0.045 inches, depending on your engine’s configuration. Always check your owner’s manual for the specific gap for your model.

That’s great info, Linda! I’ve heard that gapping closer to 0.030 can improve performance, especially if you’re running a stock engine.
I’m curious about how the gap affects fuel efficiency. Has anyone noticed a difference after adjusting the spark plug gap?
I’ve adjusted my 302’s gap from 0.045 to 0.040, and while I didn’t see a massive change, it did seem to run smoother.
I’ve read that an incorrect gap could potentially lead to misfires. It’s definitely worth checking before hitting the road!
Absolutely! It’s such an easy maintenance item that can really boost performance.
Is there any consensus on the best type of spark plugs for the 302? I’ve heard platinum ones can last longer.
Platinum plugs are great, but they might not be necessary for all builds. Standard copper may work just fine, especially in a bone stock setup!
I wonder if anyone has experimented with spark plug gaps during races? Would narrowing the gap help with higher RPMs?
Some racers I’ve spoken to suggest that a tighter gap can provide a more consistent spark, but it also might increase the chances of misfires if too tight.
Funny you mention misfires—if my 302 could talk, it would probably say, ‘Could you please stop messing with my gaps?’

Haha! That’s classic! But honestly, understanding the right gap is key for optimal performance.
The ideal spark plug gap for a Ford 302 is typically .045 inches. To adjust it, you’ll need a feeler gauge and a spark plug gapping tool. Always ensure that the plugs are clean before checking the gap!
Great tip! I also suggest checking the gap after installation. Sometimes the gap can close up slightly due to torque. It’s a good idea to double-check!
Using a feeler gauge is essential. A common mistake is not seating the spark plugs properly, which can lead to incorrect gaps. Make sure you apply a little anti-seize in the threads too!
Good point about anti-seize! I once stripped a thread because I didn’t use it. Lesson learned!
I’ve found that taking your time and measuring twice can really help avoid issues. A simple mistake in gap measurement could affect performance!
Anyone else ever experience a misfire after changing plugs? I’m starting to wonder about my gap measurements!

Yes! That’s usually related to a gap that’s too wide. Best to recheck it just to be safe!
