Description

This innovative Denso spark plug comes equipped with Denso’s patented U-shaped ground electrode.  The U-Groove forms a channel for the spark nucleus to form at the instant of ignition, which generates a more potent spark.

More importantly during regular service intervals it is wise to check your spark plugs for wear, because new spark plugs will ensure for a healthy running engine, increased fuel economy, and better response. These are the factory heat range spark plugs for your vehicle, and should be a direct fitment.

Great Plugs

The plugs are great. Make sure you check the gap though. 3 were gapped at .043 the third was .054.

Great but. . . .

I just installed these on my 05 Subi FXT. First off, they come pre-gapped but I double checked them anyway. Not sure if it was just mine but they came pre-gapped for the non-turbo 2.5L forester. No problem so I just re-gapped them and installed. Secondly, while trying to install my coils it was pretty tough to get the boots around these plugs. It felt almost as if I was jamming them in there. I took it apart a few times just to make sure I was doing it right. Only one of my coils slipped right over the plug. Anyway, took them for a quick little spin and the FXT runs great. I would definitely recommend as a stock replacement just make sure you have the gaps correctly sized.

Can't complain

Checked the gap on all plugs and they were dead-on right out of the box. I would advise everyone to be careful when removing the ignition coil connectors. I broke one of the plastic clips and had to install a zip tie to keep everything tight.

Comes pre gaped and ready to install, not to mention a great price too. Car runs perfectly with new plugs in it. Could not be happier.
