Our take on the A-Premium Iridium Platinum Spark Plugs Pack of 4

A four-pack of iridium-tipped, platinum-core spark plugs with a 5/8-inch hex and a pre-set gap of 0.039–0.043 in. They are aimed at older Toyota four-cylinders and a handful of related engines, from 1990s Camrys and Celicas to 2.4L RAV4s, Solaras and Scion tC/xB. The iridium center electrode is the long-life feature here; copper and standard platinum plugs in the same fitments wear faster and need changing sooner. The one-year warranty and the broad OEM cross-reference list are the practical draws.

Pros
  • Iridium center electrode resists wear better than copper or standard platinum
  • Platinum core adds durability at the tip
  • Gap pre-set at 0.039–0.043 in, so most installs need no adjustment
  • 5/8-inch hex and 14 mm thread fit common Toyota plug sockets
  • Cross-references several OEM numbers, making the match easy to check
  • One-year warranty
Cons
  • Fitment list is narrow and mostly older Toyota engines
  • No mention of a heat-range alternative for modified or high-load engines
  • Gap is fixed to one spec, so turbo or nitrous builds may need a different plug
  • Iridium plugs cost more than copper equivalents

Questions and answers

Will these fit my 2005 Camry 2.4L?
Yes. The 2.4L Camry is listed for 2002–2011, which covers the 2005 model. Check the engine size on your car before ordering.
Are these better than standard copper plugs?
The iridium tip and platinum core wear more slowly than copper, so they hold their gap longer. That matters most on engines where the plugs are hard to reach.
Do I need to gap them before installing?
They come with a gap of 0.039–0.043 in. Verify it with a gap gauge and adjust only if your engine spec calls for something different.
What socket size do they take?
A 5/8-inch (16 mm) spark plug socket. The thread is 14 mm and the reach is about 0.75 in.
How many plugs come in the pack?
Four. That covers a four-cylinder engine in one go.
Is there a warranty?
Yes, one year from the manufacturer.
