Review on 🚀 Enhance Performance with Brian Tooley Racing BTR Dual Spring Kit .660" for LS1 LS2 LS3 LQ4 Engines - Steel Retainers Included for a Perfect Fit by Deejay Felony

This automotive product is a game-changer. Thanks to my knowledge gained in practice, I can say that these spring retainers are an excellent addition to any performance car engine. The installation process was easy, and it's amazing how a small part like this can make such a significant difference in engine performance. The pros include smoother idle, significant gain in horsepower, and improved fuel economy. The only downside is that they are on the pricey side. However, given the benefits, it is worth every penny.
