Subaru Impreza WRX 2.5 STi, 300 ps
Advantages: Hello! I purchased this GTL kit on promo, I saved money significantly. I'm generally satisfied with power increase and fuel savings. The product itself is good. Build quality is very high. I like it, although the equipment is under the hood and I don’t see it.
Disadvantages: I was very disappointed with the delivery service. It took too much time. I was informed about another terms of delivery. Probably this issue was because of the season sale or the manufacturer, I don’t know exactly. This issue gave not so good opinion about the product.
Comment: I would give 5 if there weren’t above mentioned problem. Thanks!
