Nicholas Bonner-Williams Posted August 23, 2023 Share Posted August 23, 2023 Hi , I have a Triumph TR6 1974 125 bhp and wondered what is the best spark plug for this motor ? At the moment it has BP6ES . Thanks Nick Quote Link to comment Share on other sites More sharing options...
Tim Bancroft Posted August 23, 2023 Share Posted August 23, 2023 Genuine BP6ES are probably what most people fit and they seem fine! Quote Link to comment Share on other sites More sharing options...
thescrapman Posted August 23, 2023 Share Posted August 23, 2023 BP5ES better for PI cars, hotter plug, seem to be harder to foul, well in my experience. Even better are the Bosch 3 pronged ones, I have really struggled to foul them in my PI cars. W7DTC I think they are Quote Link to comment Share on other sites More sharing options...
TRTOM2498 Posted August 24, 2023 Share Posted August 24, 2023 NGK BP6ES are more than adequate from standard to a tuned motor. You should have no issues with these plugs in a TR6. Quote Link to comment Share on other sites More sharing options...
