yea plats are more expesive because they last LONGER, the coppers are better for nitous and FI, as they are a step colder, and are cheaper to replace. I think u can get a full set for like 12 bucks from ur dealership. VERY cheap and they work great,
are the copper ones have the same little tip like the stockers cuz i mean a tech said if i put like the ones that have bigger tip like the round ones wont burn as good as the ones are in. but if the coppers have that tip ill buy them
No they do not have a small tip like the stock platinums. Some here believe that a fatter tip will make a fatter spark. Also, copper is a much better conductor of electricity than platinum, so you'll get a better spark. The only downside is that the coppers wear out much faster than the platinum plugs (last 30k miles). But for 11.95 a set, I don't really care.
Also, if you are NA, you can up the gap to .060 and remember to put some anti-sieze on the threads before installing. Good luck.
I had one plug cracked when i replaced mine with the motorcraft ones. I had put NGK platinums in at around 30K miles. The shop who installed my blower said they put new plugs in and that was around 55K miles. When i replaced them cause my car had been idling bad and found that they were the same damn NGK plugs i had put in. Cheap, lying shop. Anyways, the AZFS22C plugs went in with the FRPP 9mm wires and it runs like a champ. I think i payed a whopping $15 something after tax, they did have alil trouble finding them tho.
