Review on 🔌 Denso SK16R11 Iridium Spark Plug - (3324) - Enhances Engine Performance - Pack of 1 by Eddie Gordon

I bought these spark plugs for my 2005 Scion XA. The Revain site listed is not suitable for my machine. The Denso website says yes. It was purchased and immediately fitted to replace the BOSCH Platinum Ir Fusion (4501) spark plugs which were causing performance issues due to the wrong heat range when they were supposed to fit my Scion. This causes excessive carbon deposits, no engine idling and poor acceleration. Attention Scion owners! These durable DENSO spark plugs offer excellent engine performance.
