I have seen too many fail with a compression seal failure. The "fine wire" center electrode, being platinum, wears a LONG time, and being a "sharp point" it fires much more easily than some other plugs. That said, I have had a lot better luck with NipponDenso platinums - also small electrode type, and even NGK, which in my estimation (and experience) is only slightly better than the Bosch. Unless they have changed dramatically in the last couple of years the nippers are still my first choice in any import engine - particularly Japanese, and more particularly Toyota. Taking all this for what it's worth, I do not replace the plugs on my 3.0 liter Ford "aeroscare" with platinums, regardless how difficult they tend to be to replace, because I'd rather change them every year or two than find them seized in after 4 when they finally require changing. ------------------------------ From: "Bruce Plecan" Date: Fri, 19 Feb 1999 20:25:53 -0500 Subject: Re: Diacom software - -----Original Message----- From: Terry Prichard To: diy_efi@xxx.edu> Date: Friday, February 19, 1999 8:14 PM Subject: Diacom software I've got a fairly resent one, e-mail me the serial numbers, and let me try them in mine.

The oil pump stopped pumping, but the motor kept running and self destructed. THEN, this guy, with no real mechanical experience decides he is going to fix it himself. Bad decision. Parts were big bucks, and his little things like rubber expansion plugs to replace block core plugs, didn't help much either. After he spent more to fix this motor than a different car would have cost him, it still ran like $hit. It never was "right" after that. On the other hand, my sister had a mini van with one of these motors and loved the thing. It went 180K miles, and now resides in the back 40 on a farm in Iowa, after it crapped on the highway one day. As far as fixing it... don't think so. :^) *********************************************************************** Dan Smith 84 Regal 12.13@112 GSCA# 1459 St.Charles, Missouri mailto:dcsmith@xxx.net mailto:dcsmith@xxx.org mailto:morepoweral@xxx.net mailto:morepoweral@xxx.org mailto:morepoweral@xxx.net mailto:smithd@xxx.com http://www.tetranet.net/users/morepoweral *********************************************************************** ------------------------------ From: "David A.

Kinda like a surface gap, type plug, while they have there place, it's in a few rather than many applications. Also, if blown out may take too long to restart the arc, and a miss occurs. Again, my theory, Often plugs wear out from deposits collecting on the porcelain rather than erosion, and air gap increases. Autolite would have to rate as a low erosion rate plug, even in the steel form...... Bruce Doc don't care how long they last, so long as they perform . >I haven't done any testing, but I suspect that the four electrode plugs >will last longer.
