Re: BTDT: Bosch Platinum +4 Plugs

[John Cassidy/Sallyann Mulcahy <jcasidy@uswest.net>]

FYI
I've run a set of Bosch Platinum +4s in my Turbo Volvo (2.3L 20v intercooled
5cyl.) for 1200 miles so far so good.  Does start easier and idle smoother, and
I may be getting 1 or 2 mpg better (its really to early to tell).
