Follow these steps carefully
The Prius v's 1.8L 2ZR-FXE takes the Denso SC16HR11 iridium long-life (Toyota 90919-01253), gapped 0.044 in (1.1 mm) — Toyota's new-plug spec is 1.0-1.1 mm. Buy four, buy the Denso OE plug, and scan for P0300-P0304 before ordering.
Let the engine cool completely; the head is aluminum. Disconnect the negative battery cable. The four coil packs sit at the BACK of the engine, under the windshield cowl — remove the wiper arms and cowl panel for working room.
I never fight the rear-facing coils with the cowl in place — pull the wiper arms and cowl panel first. It's a handful of clips and bolts, and it turns a miserable job into a straightforward one.
Squeeze each coil connector's locking tab and lift the coils straight up, keeping them in cylinder order. You'll need a thin-wall 14 mm socket — a standard 5/8 in won't fit the M12 tubes. Blow compressed air down every well before loosening anything.
Remove each plug with the thin-wall 14 mm socket. Confirm the 1.0-1.1 mm gap and matching reach to the new Denso SC16HR11 — never pry on the iridium electrode. Thread each new plug in BY HAND, then tighten to spec. Skip the anti-seize.
I've learned to thread every plug in by hand for several turns. Aluminum head, deep wells, awkward angle — if a plug binds, back it out and restart. Forcing it buys you a helicoil.
Seat each coil, refit the bolts, reconnect every connector until it clicks, then reinstall the cowl, wiper arms, and battery cable. Start the Prius v and let the hybrid cycle the engine on and off — listen for a smooth restart, then rescan for codes.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
