Spark Plugs

[alpenmac]

I want to treat Nigel Stag to some new spark plugs during his annual service. Having looked online for N11/12Ys, there is a plethora of different makes out there - some I suspect may be oriental imports of an unknown quality. Can anyone recommend a quality product from a reliable supplier? Nigel is 1973 manual o/d with electronic ignition.

NGK BP5ES is my preferred choice, never had any bother with NGK and they are widely available. Just beware of real cheapies off of eBay - may not be genuine NGK and could give problems, They are available from all the usual Stag parts people and other places like Eurocarparts.

I use the NGK BP5ES plugs and the car runs well. I bought mine on Amazon marketplace...https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1

8 plugs for less than £20. For some reason Amazon themselves wouldn't let me purchase a set of 8. Who knows why

I have used both the NGK and Bosch WR8DC+. My engine seems to run better with the Bosch (paired with Bosch Red coil) but a lot of it may be just personal taste. When I first bought the car it was Faversham who installed the Bosch versions.

Bosch available here: https://www.gsparkplug.com/1x-bosch-...g-wr8dc-3.html

Thanks Richard for the link to Amazon, interestingly it says that they are unsuitable for the Stag.

Just seen this on another forum, set of 8 NGK BP5ES from CarParts4Less (sister company to Eurocarparts so should be genuine quality) is £11.52 delivered

or £19.52 for 2 sets if you use the discount code.

Well all I know is the car was fitted with them when I bought it and I replaced like for like without any issues. I'd trust the guys on here more than anyone else.

BP5ES used to be a 1 step hotter plug than the N9Y from champion in my TR5 days and theWR8ES was its equivalent

I got my last set of NGK from Eurocarparts. They have a sale on every week, it seems, so can be picked up cheap.

[alpenmac]

Thanks for all the information. It looks like NGK BP5ES is the way to go

NGK BP5ES are currently £2.99 each from ECP. Using their SALE60 sale discount brings them down to £15.52 for 8.

Stag is not listed in their search boxes, but if you look for Triumph TR7 then you will get there.

No need - follow the link in "Marshman"s post and you get 8 for under £12!
