JJR Coil Packs Vs Oem Vs Splitfire Vs Other

[SkyHi_33]

to be honest, i like changing my plugs every 10k kms. lol

gives 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

it would be awesome to get a comparison of coilpack vs sparkplug gap vs boost pressure.

STD are the best performers but are drug money to buy new, the split fires and superspark and JJR ones are great cheap replacements.

so whats the best? Seems the Yellow Jackets have the best consistency and price......

My splitfies have been going strong for over 4 years now, haven't skipped a beat.

[SkyHi_33]

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.

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.

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]

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

[Wacky Dee]

Thanks mate appreciate your feedback..anyone else?

[Duncan]

welll without searching too hard you should have been able to find the 200+ post thread on the same topic......

I've locked this one so just post up in the other.

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)

[d_liberate]

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.

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.

is it normal for a skyline to hesitate a bit when switching gears or is that a sign of a coil pack(s) on its way out ?

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!!

Ive been using Yellow Jackets for around 11 months now and they are still going as strong as the day I put them in.

performance-wise has them on there website for around $370 delivered.

hey dennis, i have this problem too

i assumed it was my crap tune so never did much about it.

it didn't do it before the tune was done tho.

if you find the problem, please let me know.

[R32_GODZILLA]

Just purchased some yellow jackets for my RB20 off www.performance-wise.com now - I highly recommend their services! Paul is a great help and is very quick to respond to any e-mails.

Can't wait to test them out and go back to some 1.1mm plugs.
