A-Premium Set of 4 Ignition Coil Pack and Iridium Spark Plugs Compatible with Toyota Corolla 1999-2008, Matrix 2003-2008 & Chevrolet Prizm 1999-2002, L4 1.8L

What can I say? They worked. No problem installing them. Only grip is that it would be nice to include some dielectric grease and anti seize for the plugs.

Bought this A-Premium Set of 4 Ignition Coil Packs because my high-mileage 1ZZ-FE decided it wanted to idle like it was beatboxing. Let’s be real — if you’ve got a seasoned (read: elderly) 1ZZ-FE, you already know spark plugs can foul pretty easily. These engines will happily carbon up a plug and then act like YOU did something wrong. So when mine started misfiring, I figured it was time to stop pretending it was “just bad gas.” Swapped these coils in and immediately: Idle smoothed out. Throttle response came back. Engine stopped shaking like it just saw its ex in traffic. Fitment? Perfect. Plugged right in. No persuasion. Build quality feels solid too — not that lightweight “I hope this survives one heat cycle” energy. These feel ready to sit on top of a 20-year-old engine and handle the chaos. Now, let’s be honest — if your spark plugs are absolutely cooked and oil-soaked from 200k miles of life experience, coils alone won’t perform miracles. The 1ZZ will foul plugs fairly easily. But paired with fresh plugs? Chef’s kiss. Misfire who? 10/10. My check engine light is off, my idle is calm, and I no longer feel like I’m driving a washing machine full of bricks for a good bit Would absolutely buy again if my engine decides to have another emotional episode.

Fit my 2006 Toyota matrix , over a year and still going strong .

Direct replacement no issues with install. Have about 30k miles on them without issues.

Replaced original coils and plugs with this set on our 2006 Vibe 1.8L. Was running quite rough especially at idle while in gear. This set made a huge difference. These are easy to replace at home if you know how to turn a wrench. Saved a lot of money. Highly recommended.
