I decided to change my spark plugs today and called for some prices.I used the spark plug number in my manual and called Honda first.They quoted me
102.00 plus taxes for all 6.(btw...2001 accord ex v-6)The plug the manual lists is pzfr5f-11. I then called a local parts place that sold ngk and they quoted me 27.00 each(162.00 for all six).I then went on the ngk website to see what was recommended.The following ones were listed for my car. v-power zfr5f-11 g-power zfr5fgp laser pzfr5f-11# iridium zfr5fix-11 I then went to crappy tire because I knew they carried nkg.I asked them to look up my plugs because that guide they have hanging of the shelves didnt even list anything for my car....nothing after 2000.They looked it up and said Bosch platinums.I was curious why they didnt have any nkg's listed for my car. I then took my list(above)to the spark plug section.There I found ngk plugs with the numbers zfr5f-11.Notice the only thing missing is the"p"in front of that number listed in the manual? Getting a little frustrated I bought them($6.29 for 2)and took them home and installed them.The car seems to ride fine but am wondering if there is any difference in those plugs?I realize the number is almost the same(other that the"p" at the start but 1/5 the of the price has got me wondering.I changed the plugs because I am only getting 15.5 miles per gallon.Any advice greatly appreciated.
