Disappointing Performance Upgrade: Waste of Money

Based on my experience with this automotive fuel system upgrade, it did not deliver the promised results. Despite the hype, it made no noticeable difference to my car's performance. The only upside was that the installation was relatively straightforward. However, given the high price tag, I was expecting much better results. Don't waste your money on this product.

Pros
  • Improves throttle response and acceleration
Cons
  • Installation can be difficult for inexperienced users

Eco animal power! for fuel system

Bought for my 14 F150 Ecoboost. Noticed lower performance. Also increased gas mileage by almost 1 mpg. Instructions were easy to read, fairly easy installation, maybe 20 minutes. I only gave four stars because it's a bit pricey for what it is and there was no sticker on it. I also have a secure Stage 2 intake and a secure 4" tuned exhaust. They were done about 10,000 miles before I put the spacer in.

Pros
  • Internal bench tests showed the maximum increase to +16 hp. and +17 pounds. x ft of torque
Cons
  • Requires bushing

Did it really help?

Need help? With all the other modifications I've made to the truck, I honestly have no idea. Strange, I swear my fuel economy went down after installing it. I almost removed it, but after about two weeks my mileage was back to normal. Possibly bad fuel. But to be honest I didn't notice any increase. Is it worth $90+? Probably not, but in the past I've noticed a gain after installing TB spacers on other cars. Maybe I just masked the view.

Pros
  • Combination of serrated and spiral design for optimal airflow into the combustion chamber
Cons
  • Vulgarity
