''Installed the Setes® N54 to B58 kit on my coupe and wow—the spark quality is night and day compared to the stock coils. Smooth idle, better throttle response, and I’ve noticed more consistent power delivery during spirited driving. The craftsmanship is top-notch. Definitely recommend.''

''If you’re serious about tuning your BMW, don’t even hesitate, this is the conversion kit to get. Plug-and-play, no hacks or messy wiring. Performance gains are subtle but meaningful, especially when you floor it.''

''Great products and quality. Especially the coil conversion kit. This kit made it feel like it was worth the hype. Great fit, premium build, and tangible improvement in combustion. ''
