bosch plugs

[Deets]

I've resd the posts on the Bosch super 4's & just wondering if the Super Plus' ( plus Yttrium) are any good? Also with the luck I have, if they are the right ones!! The code is +7 FR7LD+ like the plus 4's these cost me £19.99

They will be as good as super4s. But I wouldn't use them as they are not multi electrode. Multi electrode plugs have a different flame front shape.

The super4 plus plugs are the same shape as a 50 year old spark plug.

I have used them.

As spark plugs go, I think they are good.
When I first fitted them, car's throttle felt responsive.

Lasted very well too.

As for which plug is better, SuperPlus or Super 4's, good question.

The Super 4's should give you a longer, more trouble-free service life because of the extra two electrodes.

Re: re bosch plugs

+7 is the correct size.

They should be priced slightly lower, about 3 or 4 £'s less than the Super4's

I think you'll be happy with them.
