Marshall was here and we were able to get some solid numbers on the headers and the air box plugs.

Here is the dyno history (steve, feel free to correct me if I am wrong):

Session 1: 407whp
- bmc filters, charc. filters removed, evo pulleys, evo diff, dinan exhaust

Session 2: 421whp
- same as above + rpi ram scoops

Session 3/4: 433whp
- same as above + evo headers

Here is the graph for session 3/4 with and without the airbox plugs. Peak power was the same basically but we saw a gain in the low and midrange like last time. There is about a 9whp gain around 5000rpm.

Plugs and scoops... should have known we could achieve such similar results from the Home and Garden section as headers alone!! :D

Congrats on bringing another cost effective product to market.

The last time we dynod with the plugs we did not do a before and after the same day. We only based the numbers off a previous session. Remember, the gains from either mods whether its 12whp or not, is that the gains are throughout the entire powerband. Peak power doesnt mean as much as how the powerband has changed.

Kenny, we all know you want to get your holes plugged. :)

Our dyno is also a motorcycle and scooter dyno. Some of you have seen how darn sensitive is...(almost as much as K's feelings). We can do before and after dyno on M5baller (before/after redbull).
