ECUtune forged pistons for NA SVXii

[longassname]

The new plugs and filter came in so I was able to install the spark plugs and the almost new coil packs. I've always used the NGK double platinum plugs or laser iridium plugs before--the two NGK plug options that have the platinum chip laser welded onto the ground strap. Denso double platinum plugs are pretty commonly available now and I decided to go with them this time. They may not have them in stock locally but they should be able to get them from their warehouse. They are a made in Japan plug and look very good to me. I expect them to be every bit as good as the NGKs. The correct plug is PK20TT or part #4504.
