I have a 2014 Ram 1500 5.7 Hemi v8. 2 days after changing the 16 spark plugs, with Bosch double iridium spark plugs (pre set gap), while driving it it starting knocking/ticking under the hood. Any advice as to what to check and how to check would be appriciated. Thank you.

 

Are those OEM spec plugs?

 

I'd verify torque on all the plugs. Also watch out for knock off plugs. Verify you bought from a credible source.
