By far the best bolt on you can do to your H22. A noticable jump in power, even from my butt dyno. Sounds alittle bit different. Well worth the money from Rosko.
Bolted on and tuned, I've seen dyno's of them making around 8-10whp. This is a midrange power adder, so don't expect huge, high-end gains.
