I think I've seen this echoed several times, but I thought I'd just take a moment to repeat that it's not worth saving $5 by buying the $4.99 Autolite GlowPlugs at Advance...... I got less than two months out of two of them and couldn't start my car the other morning. Two new Bosch plugs at $9.95 ea. and it's just amazing how easily it started. Just turned the key at 20F and it kicked right over! Still got the cheezy ones in cylinders 1, 2, and 5 though. We'll see how the rest of the winter goes!
