I got one of the 5 wire kit here. While the customer service was great, but the fitment was so-so (wrong size washer) and the actual gain from them is margainal at best (if anything). I installed the kit at the dyno, didnt gain anything. On one of the run, I actually lost 3hp, but in average it was within 1hp and 1ft-lb of each other with or without the ground kit. I guess this is one of the item that is not bad to have, but its not necessary to have it at all. I would love to look at one of those HKS kit and see if they are any better
It didnt smooth out my idle, my idle still jumps up and down
Although this is what I thought, I wasn't sure what grounding wires were for.
cjones, where is that Nascar cafe located?
It's here local in Johnson City, Tn. There is a race at the Bristol Raceway in the next town (20 min. away) this weekend, the Food City 500. Anybody watch Nascar? http://www.bristolmotorspeedway.com/
I have the blue Z-Extreme kit for over a year now and the only problem with it is that its somewhat discolored. It still looks good under the hood with the blue color but at closer inspection you can tell there is a different shades of blue.
