Walker Products 900 1650 Thundercore Ultra Review

Thanks to my knowledge gained in practice, I knew I needed an ignition upgrade for my classic car... This product surpassed my expectations in improving performance. The spark plugs fired strong and quickly, providing smoother acceleration. Unfortunately the installation instructions were not clear enough for beginners..

Works great on 2003 Sonata 2.7L Fixed my P0303 misfire on cylinder 3 (even with new spark plugs) and now it works much better, with more acceleration. They're a little long (2 or 3 inches), but longer is better than shorter. Looks very similar to the OEM. There was some dielectric grease in the kit, but it's so small it only lasts half the candles. Other sages are super lucky. Installation is a PITA as the intake manifold needs to be taken off, but there are videos on YT that will help. Good…
