Customer Reviews
Good deal on plugs
I was looking for some NGK Spark Plugs for my classic car and Green Spark Plug had a good price compared to other places. I also got a small discount for signing up for their newsletter, which helped. The shipping cost wasn't too bad, either. Overall, I felt like I got a good value for what I paid. The parts got here in good time, so yeah, worth it.
Perfect for my vintage engine!
Oh my goodness, I am so happy with my order! I got the Lodge Spark Plugs and a new set of HT Lead Sets for my vintage engine project, and they are absolutely spot on! The quality is fantastic, and everything arrived super fast, even to California. Finding these specific parts can be a real pain, but Green Spark Plug made it so easy. I will definitely be coming back for more, and I'm telling all my friends in the club about them!
Always reliable parts
Another solid order from Green Spark Plug. Got the Denso Spark Plugs for my old motorcycle, and they were perfect, as usual. Delivery took about a week to get to me in Texas, which is pretty standard. I've bought from them several times now, and they consistently deliver the right parts without any fuss. Good to know I can count on them for these older bits.
Mostly good experience
I ordered some Bosch Spark Plugs and a new Ignition Condenser for my classic. The parts themselves were exactly what I needed and seem to be of good quality. Shipping took a little longer than I expected, about 9 days to my address in Florida, but it wasn't a huge issue. The website was easy enough to navigate to find what I needed. Customer service didn't need to be contacted, so I can't comment there. Overall, a positive experience, but quicker shipping would make it even better.
Got my parts quickly
Needed some new Fuel Filters and a Fuel Hose for my old truck. Found them on Green Spark Plug. They arrived in about a week, which was fine. Everything fit just right. No problems.

How long does shipping usually take to the US? I'm in California and need some parts for a project ASAP.
Can you stack coupon codes on this site? Got a newsletter sign-up one and found another. Wondering if I can use both.
Just wondering about returns. If I order the wrong plugs by mistake, is it a huge hassle to send them back?
Thinking of doing a big order for my club. Do they do any kind of bulk discount or anything? Trying to save a bit.
Hey, I'm looking at getting some NGK plugs for my old Triumph from here. Are they actually legit NGK or some knock-offs?
