🔧 Swirltorque TBI Spacer for GM - Trans-Dapt 2533 Review

Based on my experience, the TBI spacer provides my automotive with increased horsepower and torque that is noticeable right away. I appreciate that it is easy to install with clear instructions, and has a quality build that makes it a reliable option. The only downside is that it can be expensive, but the added performance benefits are worth the investment. Overall, I am very satisfied with this purchase and would recommend it to any serious automotive enthusiast.

Installing the product proved to be a very difficult task. I put this on a 4.9 liter Cadillac OHV engine. I had to cut and bend the brake booster pipe just to clear the EGR valve, which resulted in the engine being stuck on full throttle starts. When I went to remove the gasket I found that the threads pulled out of the block were stuck on the steel mounting bolts. On the plus side, I was able to replace my old leaking TBI gasket! Thank you transdap.

As advertised, made in the USA, build quality is amazing. Noticed a significant difference in acceleration, idling and low torque as advertised. Fittings in the form of seals are also of the highest quality. Superb carving, chrome alloy finish, metal plated gaskets like the best Fel-Pro brands. I didn't need the fuel extensions as I already installed a fuel pressure tee without which you might need something, but the return line seemed long enough. You'll also need to push in the metal insert…
