lol that's the 88-89 sentra XE (hatchback). Mine was the standard two door coupe like below. I had 15" rims with 195/65/R15!

Hey, they're 20+ years old now...20+ years old = classic...okay so they're not Mustangs....

 

no mine was an se not an xe

anyway off the crappy nissans. so i've always had this question bout plugs. i know you can get copper plugs and find hotter or colder plugs. can't you just get platinums that are basically an auto range plug and works for both hot and cold?

 

Actually, Platinums also come in hotter and colder range plugs. There are just fewer choices than copper plugs.

 

Motorcraft carries a wide range of plugs to fit every application. You don't need to venture out to Japanese plugs tto get quality plugs for your classic. http://www.fordpowerproducts.com/products.do?item=18

 

Oh I know that, in fact I wouldn't even touch those plugs with a domestic. Go autolite platinums all the time but I was just wondering if they're differances better getting a hot plug/cold plug or just getting platiums which are said to basically be auto ranging

 

Never heard the term 'Auto ranging' a plugs heat range is basically a design of how far down the porcelain core goes before it attaches to the outer shell of the sparkplug. Keep in mind, jap plugs have their indexing backwards. Higher numbers to them mean colder plugs. So for domestics 45 Autolite is colder than 46 Autolite

 

well when I was working for schucks they were telling us that they sell old style copper autolites that you can get hotter or colder plugs but they don't for platinums becasue the platinum material heats up differently and their not such idea of a hot/cold platinum plug


maybe I was taught wrong?

 

Yeah, the old autolite 42's and 45's are copper core. Platinum is not necessary on a stock 289 engine unless you want to run those plugs for 100K miles.

 

EVERY test I ever read said they were no better than stock. I have used th Bosch +4's and liked them...they NEVER fouled, missed and I ran them for 100,000 miles.
