HOW OFTEN DO YOU REPLACE YOUR COILS/PLUGBOOTS

09 base Taco 2.7 auto 147k--------------- this is my first vehicle with coil packs or a coil per piston. in the past I would just do a plug ,wire dc cap and points change and call it good. if and only when the coil went bad it got replaced. so my question is what is the lifespan in miles of these newer coilpacks.

 

This. "If it ain't broke, don't fix it" applies here.

 

Usually a long time. The truck will let you know when it is time with a CEL.

 

Ignition parts seem to last a very long time in modern cars. Had a chevy truck with 186,xxx miles on it and 13 years old that still had the original wires and coil pack. Another chevy was 8 years old and 200,xxx+ and still on it's original wires and coil pack. My Honda Accord was 8 years and 125k and still on originals.

I remember when ignition parts needed serviced every 10-15k miles back before many of the readers here were even born (60s, 70s and 80s).

Yes, I'm that old...
