Aiden, you shouldn't make statements like that without doing the research. Genuine coilpacks about $480 + postage from Driftmotion in the US, I got mine from them. I guess you should be really surprised as that's about $340 cheaper.

Shane they never claimed them to be better than the splitfire coils, they're just pointing out that theirs make .1hp less than another more expensive brand
Id say the "possible 11kw improvement at the wheels" would be compared to factory coils

ComPared to 20 year old coils . Even super spark could made no difference in performed over factory ones , they just offer something readily available locally .
Thanks Jeff , could remember name of drift motion also as an option

There r several 800+ hp 1 and 2jz motors running oem coilpacks there are also a few 800 hp rb motors running toyota oem pack as well. You can't beat oem parts. I would have brought oem when mine died but I didn't the $1000 spare at the time and I didn't know about drift motion

A couple of years ago I contacted a company in china that made coilpacks, they worked out costing $12 each AuD if you bought 300 of them. I would say that's where a lot of the cheap coilpacks come from.

I am running these. I contacted the seller to get them developed so there is some more competition on the market. I had new OEM coils and replaced them with Yellow Jacket (threw the oem in my other car) and honestly had no loss in performance if anything it felt a bit better. Not having the car on a dyno at the time I can't say there was a power increase but definitely didn't lose any. So far I have done just over 5,000km on them and runs like a dream.

In my defense: "possible 11kw improvement at the wheels" is not a claim we make for ALL vehicles. When we initially tested the coils on an R32 GTR we had an increase of 11kw after installing the YJs in place of 20 year old stuffed OEM coils. This is what most people are replacing when buying new coils.
"and then they clearly put up two dyno graphs showing that they'll actually make .1 of horsepower less compared to another brand." The point we are making here is that the YJs will give you a similar result but at a fraction of the cost. This means a lot to some. We never claimed the coils were better than the other blue ones. Just that they are on par.

Hi and welcome Paul. Good on you for putting in an appearance. Can you give us any background to the yellow jackets? I have assumed that they are made in the same factory in china as the red ones are, but of course i could be wrong. In New Zealand, the yellow jacket ones ar marketed at $640 per set, whilst red ones can be had for around half that. Your thoughts? all the best with your business ventures.

I just reckon it's pointless comparing new coils to old ones, if you had a car with coils with major cracks that could hardly come on boost, then did back to back dyno runs with replacement coils you could even claim 70rwkw difference.
I think it's just a marketing term to get people to want to buy them as everybody gets excited when they hear about power gain.
I'd be more interested in reliability , fitment, construction etc.

I know this started off as on old thread resurrection, but I have to agree with Boris in that you have to test like with like & especially when the term 20 year old stuffed OEM is used comparing it to New yellow jacket's fitted & I'm surprised it was only a 11kw gain ..
And again long term reliability is another very important factor too which is the unknown ..

I am the trade mark owner of Yellow Jackets Coil Packs which is about 5 years old now. I work very closely with my agent in china to produce decent quality, reliable coils. I can vouch 100% that Yellow Jackets are NOT made in the same factory as the red, black, pink or blue ones on the market. We are independent of those others and we strive hard to give out the best possible product that we can. I personally pack and distribute every single set that is in circulation, worldwide and nothing gets past me. Our Yellow Jacket YJ-1JZ2JZ coils have been on the market for around 2 years now and I've sold around 115 sets worldwide. That's around 690pcs. From this 690pcs I have had exactly 5 coils exchanged under warranty in the last 2 years. Before we released the YJ-1JZ2JZ coils to the market, we did extensive tests for fitment and reliability and they performed quite well.
I'm convinced these coils will stand the test of time and we offer a 2 year local warranty to back this up. Fitment is perfect and construction is quality. I'm not going to claim 70kw when the result we got was 11kw. I'm not going to lie to sell my products. They sell them-selves and I'm doing quite well as a result. It isn't pointless comparing new coils to old as most people wouldn't go out and get another set of old, 2nd hand coils on their car just to have them most likely fail in a few months time. As for the NZ market, I don't have any say on how my distributor in NZ sets his prices sorry. He is a sole distributor and he has overheads etc..
I know the product is still relatively new. I had the same questions from the Skyline guys when I started out 5 years ago and there are people that started with the first batch of coils who still have these running on their high HP GTRs. I will still be here in another 5 years time and hopefully the rep of YJs will have improved and we will stand out as more than just a China made product. Hell, what isn't made in China these days??
