    • Scion got a little smoother and lot zoomier
I bought my 2011 xB this spring. I wanted a smaller, and more economical, daily driver than the Sport Trac. It's been fine but as a car guy (well, lots of British cars) I knew it could use some care and feeding. I have concentrated on non-engine work as I got through cancer treatment. This week I finally started on the engine work. The car was pretty laggy on accels and the MPG was several miles below the original 24 combined rating. I haven't worked on a Toyota since my bought-new '71 Carina. I figured I would just start with the usual easy suspects and go from there. So spark plugs it was. I chose to go with these Densos, which were the OEM versions. They came quickly, and the gaps were preset correctly (yes, I did verify each one). Install was quick and easy. I admit I've been pushing the car a little harder in the three days since. The car has some improved jump accelerating from stop. But where I notice the big gain is top-gear acceleration, like from 50 to 65 MPH, or 60 to 70, It's more responsive, quicker, and smoother. It's not straining or stumbling. I have to note that the old plugs were done for. They looked like they were the originals from the factory. Their center electrodes were all pretty much nubs. So I expected a big boost in performance. And I'm satisfied I got it with the new Denso plugs. Hopefully I will also see some improvement on mileage ... but I'll need to stop pushing the engine so hard before I can determine that. Soit might be a while before I provide that update. ... show more
