Need to replace the lambda sensor on my coupe gt 1991 on a 3 f engine. Anyone recommend a quality product but, at a reasonable price. Link to eBay would help please.

Try this one.

I've started ordering parts from this KMS place after a recommendation and everything turns out to be the genuine part, not a cheap remake.

Much appreciated. Thanks

These work just as well, just don't have the plug. Is the plug really worth £40 more?

Ensure its branded (I prefer NTK) but unless you need it with the plug wired for you - take your pick.

Ok. Thanks for your comments.
