What are the best spark plug brands out there?

I’ve heard mixed feedback on Autolite. Some love them, others not so much. It’s a tight race between several brands. What’s your driving condition like?

I’m mostly city driving. I just want something that doesn’t require too much maintenance. Going to give NGK a shot since so many are recommending them!

Good choice! I’ve been using them for years with minimal issues. Remember to check your gap and you should be golden!

So, which brand has the best warranty? I was looking at some options but didn’t find solid info. Anyone have insights on that?

You know, I don’t think about warranties much, but I heard ACDelco has a decent one. That could give you peace of mind if you go for them.

I’ve had great experiences with NGK and Bosch spark plugs! Just make sure to gap them properly and use a torque wrench for installation to avoid striping threads.

I’ve also had luck with Denso. And yes, proper gapping can solve many ignition issues right after installation!

Don’t forget to check your ignition coils too! Sometimes, if they’re faulty, it can lead to misfires even with new spark plugs. Installation can be simple, but troubleshooting is key.

Great point! Misfires can often be misdiagnosed as bad spark plugs. Always check the whole ignition system!

I recently installed some Autolite plugs and found the installation very straightforward. Just remember to use dielectric grease on the plug wires to prevent moisture issues!

Very helpful tip! Also, be careful not to overtighten; it’ll save a lot of headaches down the road.

If you notice a rough idle after installation, check your spark plug wires for any damage. A bad wire can lead to performance issues that are easy to overlook.

Exactly! And sometimes, a little oil can get on the plugs during installation. A clean surface is essential.

I’ve read that spark plugs actually have a shelf life too, so even if they’re new, check the date on the box! You don’t want to install old stock.

Wow, I didn’t know that! How do you find out? Is there a specific number to look for?

It’s printed on the packaging, usually a date or a code. Always check for that! And don’t forget to apply some anti-seize compound on the threads of the spark plugs to prevent sticking.

Good advice! This is not just for easy removal; it can help ensure an accurate torque setting too.
