Best place for NGK BPR6ES?

[Technoholic]

I've found some places selling these half the price of others, do there tend to be fakes of these plugs around? Where would you recommend buying them from for the best price?

Thanks

[Sardonicus]

Lots of fakes both NGK and Denso I would be careful with Ebay as this seems to be the most affected if you dont have a Euro Car Parts of GSF near by then these are good guys https://www.gsparkplug.com

Thanks, I've got an ECP nearby but their prices are quite high, relatively speaking.

I've got another local motor factors though who I've just called and are not too badly priced so I might just pop down there and pick them up.

Perfect, ordered, thanks very much!

You can use them but they are 1.1mm wide gap type (the 11 in the model number) and when you close the electrodes down to the TVR gap they are slanted far from ideal but they will work , dont however leave them gapped at the pre-gapped boxed setting

[Technoholic]

Ah, I don't have any feelers and I'd like them to be optimised rather than compromised. Maybe I'll cancel that order if possible and look for the correct ones

[FlipFlopGriff]

i'd never noticed how many types there are of BPR6ES. I've checked back and I bought some from ECP but they seem to be without the -11. Got the iridium ones in the pre cat now but will have to check the 500, although if they are the -11's its pulling like a train with 335 torque and 313 Bhp,

Buy some feelers, they are cheap and you might like to reduce the gap on the correct spec 6 grade plug down to about 0.8 mm or it might be to much for the little old coil. You can go to 1mm with an after market Ecu using coil packs as they provide a superior amount of power to each plug for the spark

A larger gap than recommended which is about 7mm on standard plugs can cause firing issues at higher revs as the coil can’t keep up.
Using the standard coil stay close to recommended gap size is the best advice.

I think 7’s come with a gap at about 0.7 mm so the 6 is likely to be about the same but I’d be checking the gaps before installing to be sure.
Misfires and odd running can be a pain, doing all you can to eliminate things as well as things you do yourself is very important or you can end up wondering in circles.
As your a new owner you’ll slowly learn most of this and if someone hasn’t mentioned it before ROVERGAUGE is a vital tool to help see what’s going on and narrow down issues rather than just replacing and doing it the old school way. Saves a lot of dollar.
You’ll need a knuckle joint and short extension bar and I use 3/8 drive socket set to remove plugs or the rear ones as it’s a tight squeeze. Just makes it a lot easier to remove. Enjoy your new toy

NGK come pre-gapped for the application , yes lots of variations if you want cheap but a higher spec plug than the S type then fit BP6E or BP6E -VG they have a grooved electrode no need to fit resisted plugs and suppressed leads however with the Lucas system

By rights I should know that as I’ve changed a few, yes they are pre set but I always check em anyway

Scrap all that above then as they should be the right gap

I fitted BPR6EY at the start of this season and ditched the extenders and used titanium heat socks. The Y indicates a V groove in the central electrode. Seems to run better than before but that might be more due to ditching the extenders but the V groove is supposed to enhance the flame front. Don't know if it's fact or hype but they didn't cost any more from Eurocarparts so thought it worth trying.

Thats an 80's Honda plug fitted enough of em back in the day

[Technoholic]

I've managed to get some BPR6ES from my local motor factors. I got the resistive plugs as I'm going to remove the extenders (3 have already been removed by previous TVR specialist to try to rule out an issue, and socks are already on all of them).

While I'm at it, I'm going to replace HT leads and probably coil and amp.

Which leads to people recommend? I've seen various discussions about them. Also for the coil, that seems easy to get hold of, but the amp part that you can buy easily seems to be a modern version of the original that I've heard people say is not great. What is the recommendation for a new amp these days?

In my experience the best leads by far are.....

MSD Superconductors..

[Belle427]

The problem with fancy leads is that if one burns or breaks down they can’t be bought singularly, the Msd leads are very high quality though and designed to take some heat.
I have them fitted with the dei heat socks so hopefully they will last well.
I’d be tempted to try some good quality standard leads and the best quality heat socks.

^^^^^^^ this


Keep it simple and effective.
