Customer Reviews
Good for my truck
I got a boitier additionnel for my utility truck. It shipped pretty fast, took about 6 days to get here. Made a small but noticeable difference in power, which was cool.
Quick shipping, solid product
I ordered an admission directe kit for my car. The ordering process was straightforward on their site; I found what I needed without much fuss. Shipping was faster than I thought, just took 5 days to reach Denver, which was nice. Packaging was secure, everything arrived in good shape. Installation instructions were clear enough, and the kit itself felt like good quality. After putting it in, I could definitely tell a difference in the engine's sound and a bit of a performance boost. Customer support answered a quick question I had about compatibility before I bought, so that was helpful. Overall, a smooth purchase and I'm happy with the product.
Happy with engine module
I've ordered from Speed Power a few times before, mostly for my other cars. This time I got a boitier de puissance. Delivery was consistent, like always, arrived in about a week. The module worked just as expected, pretty similar to the last one I installed. This is why I keep coming back, they're reliable.
