Balboa reported a smoother idle and some performance benefits with Pulstars. Others had similar results, but have also had reliability issues too. If you think $25/plug + potential for slight performance and/or pre-mature failure is justified, then go for it. Personally, I'd rather apply the $100 for a lightweight fw and clutch upgrade.
I run NGK Iridiums and that'd be my recommendation.
