Q: Are these denso (4709) iw20tt spark-plugs delivered "pre-gapped" to the customer?

As in any spark plug (SP) user, you should always check the gap. The same SP could be used in different engines and/or applications. So, BE EXTRA CAREFUL GAPPING these SP because the center electrode is .040 in dia. Will snap off very easily. I put them in a vice with vg light and carefully gap to what I need. I use non-nickel anti-seize on the threads whether the heads are aluminum or CI. Torque to factory specs. Good luck
