SkyHi_33 Posted July 19, 2009 Share Posted July 19, 2009 to be honest, i like changing my plugs every 10k kms. lolgives you the opportunity to check their condition, spot any warning signs, and give the whole area a once over. i'd feel weird not looking at them for 100k kms, if they infact would even last that long. +1 i crack mine open every 5,000kms to check up on em, replace at 10,000kms. better be safe then sorry Link to comment https://www.sau.com.au/forums/topic/187108-jjr-coil-packs-vs-oem-vs-splitfire-vs-other/page/11/#findComment-4723437 Share on other sites More sharing options...
RaZ_TuRbO Posted July 21, 2009 Share Posted July 21, 2009 it would be awesome to get a comparison of coilpack vs sparkplug gap vs boost pressure.

AAIP Posted August 27, 2009 Share Posted August 27, 2009 STD are the best performers but are drug money to buy new, the split fires and superspark and JJR ones are great cheap replacements. .

SkyHi_33 Posted September 11, 2009 Share Posted September 11, 2009 splitfires have been tested and proven, yellow jackets are probably the best ones for money out there. so far ive had the car up to 14psi on 1.1 plug gap with no problems. They came packaged properly, they fit perfectly and perform great. And you get warranty. For that money, not much more you can ask for.

Wacky Dee Posted September 14, 2009 Share Posted September 14, 2009 Does anyone know where the Splitfires are actually manufactured ? Is it Japan ? Set of splitfires on ebay is $600 yet the market's been flooded with all these yumcha $300 coilpacks resold under various brands .. I believe they ALL probably come from the same chinese manufacturer. Justjap sell them, performance-wise sells them and there are a few different companies on Ebay that sell them and each one gives them a different brand name but to me they look the same. Some are different colours but I think that's just part of a ploy to try and fool consumers into thinking they're from different manufacturers. Anyway, what's everyones experience been with these Yumcha coil packs that sell for $300 on Ebay ? I've read some good but also a few negative posts where they either came DOA or one or more coilpacks died after only a short time.

spec-V Posted September 14, 2009 Share Posted September 14, 2009 Ill clarify from personal experience on my own cars. I had RB25DET R33. Usual misfire, coilpacks blah blah blah. I too tossed up between splitfires ($800 at the time) and the JJR ones at just under half price. Money was tight and I went the JJR's, worked excellent for 6 months brilliantly, replaced plugs 2 weeks after install and the car went even harder! Was so very impressed! Unfortunately one coilpack malfunctioned at about the 8 month mark, jumped on the phone to JJR, they sent me a new one and even re-imbursed postage. Over a year on and they are still going very strong and very happy with the product. People claim to have dyno'd splitfires against china brand and have found 5-10hp difference, but personally I think its a crock of shit with people trying to make there china product better than the real deal or another china brand All in all, I was very happy with the product apart from the little mishap and would definately use them again as they solved my problem and gave me better performance and fuel economy. And as always, the shit under the bonnet of your car is nearing 20 years old, its brittle and will break, be gentle! Especially with your coilpack harness. I learnt the hardway. Goodluck, for more info do a search I did a writeup in someone elses topic early last year. This topic has been covered!

spec-V Posted September 14, 2009 Share Posted September 14, 2009 I just thought I should also add. I have installed 2 more sets off JJR coilpacks into mates RB25DET powered vehicles and one set of another brand of china pack in a RB20DET All three sets have worked faultlessly to date and they are well over a year old also Link to comment https://www.sau.com.au/forums/topic/187108-jjr-coil-packs-vs-oem-vs-splitfire-vs-other/page/11/#findComment-4826255 Share on other sites More sharing options...

Wacky Dee Posted September 15, 2009 Share Posted September 15, 2009 hm it seems JJR and YellowJackets don't sell any coil packs for R34 GTT's where as SuperSpark do ... I used to think they are all the same chinese coilpacks rebranded but doubt it anymore. If Supersparks were made in the same place as the others, the other sellers would have R34 GTT coilpacks for sale by now. But anyway ..only a $50 difference between Superspark and Splitfire so might as well go Splitfire if you have an R34 GTT/Stagea (NEO motor) Link to comment https://www.sau.com.au/forums/topic/187108-jjr-coil-packs-vs-oem-vs-splitfire-vs-other/page/11/#findComment-4826674 Share on other sites More sharing options...
d_liberate Posted September 15, 2009 Share Posted September 15, 2009 from what Ive looked into they arent made in the same factory. Ive also heard that there will be some R34 RB25 NEO Yellow Jackets on the market very soon. Id assume the pricing would be the same as the other yellow jacket models too. This is great news as they are about $100 cheaper than supersparks and about $150-200 cheaper than splitfires.

Beer Baron Posted September 15, 2009 Share Posted September 15, 2009 well i have used OEM on a number of my cars. splitfires on 2 (about to be 3 next week) and other branded chinese ones (like superspark, JJR etc). my experience. most OEM ones have been fine, but I did eventually develop a missfire in one car that was fixed by a set of splitfires. I've never had a splitfire coil fail and used them in one of my GTRs for a number of years. and one set of them I bought was second hand so used for who knows how long before I got them. they are good quality and work just as promised. I can't honestly say they give any more power over a properly functioning oem nissan coil. the problem is though most of our oem coils are pretty old and not at their best so it's not un-usual to get an improvement when switching to splitfires. as for the other 'brands' with the various colour chinese made coil packs. my experience has not been so great. they worked ok for about 10 months, then 1 failed. luckily they do have local service cause you might well need it! in their defence the coil was tested and promptly replaced. things were fine again for a while. now they again have a light miss that goes away when I swap them out for a set of OEM coils. so we'll see what happens from here. i won't name the 'other' coils as it's not really fair as they have at least stood behind their product. but it's still annoying having them fail and take your car off the road. for the money they are I guess reasonable value. but I do think the splitfires are a better product. are they $XXX better? I can't say for sure. Link to comment https://www.sau.com.au/forums/topic/187108-jjr-coil-packs-vs-oem-vs-splitfire-vs-other/page/11/#findComment-4827034 Share on other sites More sharing options...

Does anyone else have anything to add with long term use of the cheap chinese coil packs? I'm leaning toward getting a set of the yellow jackets but wondering whether it's worth spending a little extra on Splitfires. It would suck to have a $400 set fail a month out of warranty!!
