Installation Time: Less than 1 Hour

Good product, easy install
Decided to change my plugs out at 30K miles. Old stock plugs had lots of carbon build up and looked pretty worn out. Getting the old plugs out and new ones in was a breeze, but I took my time so finished it in about 2 hours. Didn't notice any performance gain, but acceleration is smooth. AM prices on these plugs is very competitive.
