Review on 🔥 Improved Denso 3461 Spark Plug: Achieve Better Engine Performance by Jun Merritt

My 2010 Acura TSX had just clocked 99,000 miles and although the car was running great I thought it was time to replace them. Acura's scheduled maintenance says they need to be replaced after 110,000 miles, and these are the same plugs that were OEM with the 2010 car. When I took the candles off they looked amazing as they had almost 100,000 on them. Inserting new ones was easy. So when I went for a walk with new spark plugs. Oh God. It worked better, smoother, faster. Pickup became more responsive. I'm very impressed that they lasted up to 100km but I think I should have replaced them at 75km just to get the car running better. It really works like new again.
