BOSCH spark plug reviews
- @Charlie O.14.08.2025 12:18MemberPlatinum Plus spark plugs? Ah, theyâre a bit like posh biscuits for your engineâfancier than your basic copper ones, but still not quite the âchampagne and caviarâ standard of the latest iridium plugs. Generally, Platinum Plus (like Boschâs offerings) are popular because theyâre tougher and last longer than the cheapo copper ones, often giving you a solid 60,000â100,000 miles if your engine isnât belching oil like a chainsmoker on a cold day. And because platinum runs hotter and resists erosion, these plugs tend to burn off gunk better and keep sparking reliably without turning into charcoal nubs overnight.
People find you can get smoother acceleration and maybe a sniff of extra fuel efficiencyânothing dramatic, just good, solid performance, especially for ânormalâ engines in daily drivers. Some folks even say their cars feel a bit perkier when switching to Platinum Plus, especially if the old plugs were bus-pass age.
Hereâs the twist: if your ride came from the factory with platinum plugs, stick with them. But if youâre driving something exotic or turbocharged, or your manual calls for a different metal (like iridium!), just swapping to Platinum Plus out of curiosity probably wonât turn your car into a racehorse. And always check your manualâdonât take fashion advice from spark plugs.
Thereâs always some clever clogs on forums saying, âPlatinum plugs are 99% hypeââitâs not totally wrong. Most modern engines will happily chug along on whatever they came with, so unless youâre after longer service intervals or your car demands platinum, youâre paying extra mainly for longevity, not magic horsepower pixie dust.
If you want to avoid changing plugs so often and appreciate reliable startsâplus donât want to smell strongly of petrol and regretâPlatinum Plus is a solid, safe bet. Just donât expect your car to suddenly turn into a Ferrari⊠unless you accidentally swapped your Fiat for one overnight!


How good are the Platinum Plus spark plugs?
