Pulstar Pulse Plugs
Pros:
Changing spark plugs for more power? Yeah, that's our kind of mod! Installation took 10 minutes (because we're slow), and power gains were realized across the board, most noticeably in the top end.
Parts:
Plugs, crush washers
Tools:
10mm and 14mm spark plug socket, extension, anti-seize compound, and wrench
Installation Time:
10 minutes
Notes:
We have to admit, we were a little skeptical about these things when we first saw them-another spark plug gimmick promising to make power? Please...but, when we actually read up on how they work, and saw that some reputable tuners were making power with them, we had to try. The consistent, across-the-board power gains the plugs made were a result of improved combustion, meaning not only more power, but better fuel efficiency too; a win-win for the street car. And considering the efficiency of the K-series' ignition system to begin with, we'd expect even bigger gains from installing them in older, larger engines
