    Service writer just tried to say I need to change my spark plugs. I only have 32000 miles on my 2016 1500 5.7 Hemi. Seriously?

    it states in the owners manual for my 2016 Ram 1500 5.7, to change the spark plugs at 100,000 miles and...
    "the spark plug change interval is mileage based ONLY, year intervals do NOT apply"
    This information is located on page 271, of your owners manual. Take it in and show your service writer what an ignorant ass that he/she is!

    The only time you would need to change the plugs before 100000 miles (although I never even come close to waiting that long) is for a blown head gasket or intake gasket where coolant and oil mix together or something really fouls them out. He would need to show you proof of why and the Iridium plugs do not show wear easily! You would want to see a gauge in the spark plug to show you that the gap is way too big. I don’t know what the gap is for your truck off the top of my head though.

    Never go back there. Even if you had a pre 14 truck, the interval was 36000 miles.

    service writers are paid to lie- most do not understand how to work on a vehicle, take time to talk to one and you’ll figure that out.

    I changed mine last week in my 2015 hemi. I have 65K miles and was starting to throw a code for cylinder 1 misfiring. The truck is heavily modified with a custom tune, so it wasn't really a surprise to me. I went with the Bosch double iridium due to local availability. Truck has been running great now.
