Yup, I have these, what did you need to know....

 

i was interested in these, notice any power gains or is it mostly for reassureance of having more than enough ignition spark? ive heard they are more beneficial for FI setups but i wonder if the would give a NA engine maybe 2hp? 5hp? none?

any long term negative side effects on engine or igniton? nice clean plugs?

 

Well, I do have FI so I can speak for that ,and for me there is some power gains maybe 6 or 7 HP but the engine feels smoother under accceleration and through-out the gears.
Truly because I have not had a chance to get it dynoed it's hard to say how much I've gained.
I know a few guys here on the fourm that are NA and they use them as well so you would have to find out from them what there opinion would be.

 

I have only noticed slightly better fuel economy and better throttle response. Approximately 280 miles on a full tank of gas (mixed city/highway driving).

Thank you guys for your feedbacks. I was busy around lunch time today. Just got an email from Akira Sato from Okada projects. He said it is ok to use the plasma direct coil-over plug with Pulstar plugs. I was worried about negative results for using these 2 together. Akira also said if you have supercharged/turbo, you have to use different spark plugs. I agree with Tan about the plasma coil-over plug. The engineer guy I know is in Vietnam right now. I wait until he comes back to confirm with him. How is the Bruno Magli shoe? I used to have the $600 cap toe from them 2 years ago. I returned it because Bruno Magli does not refurbished their brand. They send it to a subcontractor, the materials are not the same. I have Mephisto casual shoe now, it is comfortable.
