Great spark plugs good price
Verify your gap on plugs as I never trust the gap always verify it for your car. Good quality price is lower than plugs at the auto parts store. Easy to install, so far I have had great performance with these plug. Plugs are durable and last just do correct gap to plugs.

Well made and economical, my only issue is they’re not pre-gapped.

Make sure you gap them!
Decent plugs for the price, but make sure you gap them! Gas milage seems good. They don't come pre-gapped. I Assumed they did and threw them in the Audi A4 as i couldn't find my gap tool. The car started, idled and drove fine but stuttered badly when hard accelerating. I pulled the plugs, checked the pre-set gap and they were well over spec. Decreased the gap and now drives perfect. I'm used to the pre-gapped auto parts store plugs out the box, my bad. Overall good plugs as long as you keep that in mind. Too early to tell how long/how well they'll perform.

WORKED LIKE NEW PLUGS SHOULD! GREAT VALUE!
These were perfect! Will buy again!but... don't get me started on what a piece of crap the 2004 Dodge Stratus is when it comes to retrieving the broken old sparkplug down in the valve cover hole. Thank god the ceramic didn't break! Crisis averted! Ha Ha Ha! Love our NEW plugs!

Plugs are cheaply made. 2nd set first lost in shipping. Paid for two day shipping got 5 days late. Still waiting on rest of order. Just wondering if this will work.
