I used a lot of Britpart items on my show-winning Discovery 1.5 3.9 V8i and never had an issue. Never used anything electrical of theirs, which I know people who have had lots of issues with.

Put a britpart rad in my 4.6 early summer (after seeking advice on here) and also top rad hose. Been fine so far (only a few months I know, but done about 5000 miles) with a noticeable improvement in temp (no more fluctuations even in scorchio weather and sitting in traffic). Top hose was fine didn't need to cut it down and seems good quality rubber.
Yep, road here are ****e, think off roading is probably a smoother drive.
