Hi,

Do you know if that also applies to coils sold by SNG Barratt UK?

Cheers

WHY do these coils go bad??

what is in the design system that makes them a weak link!

i have used many coils over 40yrs old ,no problems.

 

sorry I should have moved much earlier but I haven't, I have to ask TRW Japan asap.

ronbros, they go bad because they are mounted in a hole in a cam cover and exposed in heat all the time. When the inner insulator plastic cracks because of the heat, they die. Plus there seem to be a lot of Chinese made coils in the market, which might be a biggest problem.

 

Hello Jonathan,


Yes we list the same products across all of our branches. Providing you order the coil designated with a # you will receive the OEM 'Made In Japan' coil.


Be sure to mention JaguarForums and I'm sure they will discount the order

 

Isn't it great to have a forum vendor helping out on the site, offering parts and services as well as advice AND discounts to members?

Kudos to you SNG Barratt

 

Oddly, when you navigate through the website's menus, it shows the "X300" as "1994-1997 MY", which is incorrect. (or I've been misinformed all this time )

 

Where? Just wondering.

It doesn't matter much, though. In the USA the X300 model run is very definitive: 1995-96-97 "model years". That's it.

Elsewhere in the world, not so much. For some folks the "year" designation is when the car was first sold. For others, the year of manufacture.


This will always be a bit of a bugaboo.

No biggy, but I find it odd this is the first Jag Parts place that listed the x300 platform as year models 1994-1997. But as you state, it's not a big deal, cause we know it's 95-97

 

Silly me, I thought you were referring to something that you saw here on Jaguarforums.com

It also dawned on me that my posting might be interpreted as suggesting your remarks don't matter much. That's not what I meant . What I meant was the model year issues/confusions always will pop up no matter what anyone does, for the reasons mentioned.

This is what comes of posting before my 2nd cup of coffee.

They've mixed up calendar years and model years. MY95 started in September '94. MY97 finished in August '97.

 

SNG Barrett I believe is a British company and in England we typically think of car years based on purchase or manufacture date. We don't really have a concept of model years like here in the states.

 

One thing that may be causing premature coil failure. When I bought my car at 65K miles I went in right away to check plugs. Much to my surprise the previous "lug nut" that was in there did not put the coils back with gaskets. No gaskets means higher heat transfer. I also think one should use a grease on the gaskets such as a dielectric. Grease will further insulate the coils from heat as well as reduce the static electricity transfer that causes cam cover electrosis.

 

Yea, I'd really like to know what happened to my Cyl #1 [cam cover] spark plug bore. It sure looks like it was zapped with some heavy duty arcing (the associated coil is just over a year old, with no cracks). From my recent post (oil in plug bores), showing obviously what is more than just "corrosion":

Here's a link to a forum thread discussing this issue back in 2010:
X300 Camshaft Cover Corrosion

I have a question for the group:
What about wrapping each coil in some sort of "spark shield" cloth? My knee-jerk thought is to use some HeatShield cloth I've bought from Summit racing (for another project), but it's aluminized, so not sure that's the correct solution.

.

 

Probably not coil on plug - that's a relatively recent invention. These coils live inside the cylinder head where it gets pretty warm.

On the up side, we don't have a distributor or any HT leads to get wet.

 

YAY!

Just got the coil today and am 100% satisfied that it's 'the real thing' . It has the correct label and even the amber-colored (as opposed to black) potting compound.

My hat's off to SNG Barratt

Finally they gave me an answer...

It will take a little more for me to be able to start providing the Japanese X300 coils, but I will be able to offer them at £49/$81 including shipping cost from Japan to worldwide.
I can give some discount to multiple purchase(for the shipping will be cheaper when I send several coils together) .

If you are not in hurry and can wait for a month or two until I get in the coils, when you make a reservation and I will give 5% off from the total price.

Again, I guarantee the coils I offer are MADE IN JAPAN.

Hope you guys like this offer...

 

Well done Ikuma,
It would be excellent if someone can offer genuine OEM ignition coils for X300, as well as SNG Barratt. We all know these coils are a bit of a weak point with these engines, along with the cranks sensors and the lambda sensors.

 

Does the long tube that connects them to the plug screw on? Luckily, I haven't needed to investigate this issue.

 

I believe you're referring to the rubber "boot". The coil consists of 3 components:
* Coil
* Insulating rubber boot (not screwed on, simply pushed on)
* Spring connector (inside of the boot)
