Customer Reviews
Always reliable for my EFI needs!
grabbed the 7-inch Digital Dash this time, and like my previous orders, it shipped out super fast. aces efi is always consistent, unlike some other places where shipping costs can jump around a lot. plus, they answer my questions about shipping to canada pretty quickly too, which is a big help.
Fast shipping, product works
Ordered a 7-inch Digital Dash. Shipped quickly. Got it in 3 days. Install was simple enough. Screen is clear. Works as advertised. No issues.
Easy upgrade for the old truck
So I decided to finally upgrade my old pickup from a carb to EFI. My buddy told me about Aces EFI. I just went with the Killshot TBI System because it seemed straightforward. The website was easy to use, nothing confusing. It got here pretty fast, maybe 4 days after I ordered it. Installation was surprisingly not too bad. I watched a couple of videos online, and the kit came with decent instructions. My truck starts up way quicker now, and it just feels smoother driving around. No more cold start issues. It's a solid improvement, glad I did it.
Good value for a complete kit
I was looking for an EFI conversion for my classic and stumbled upon Aces EFI. The Jackpot EFI System caught my eye because of the price. I compared it to a few other brands, and this one offered a lot of features for the money. I signed up for the newsletter and got a small discount which helped. Free shipping for orders over $99 was a nice bonus too, saved me a few extra bucks. The kit arrived in about 5 days which was pretty quick for a larger item. Everything in the box seemed well-made. Installing it took a weekend but the instructions were clear enough. My car runs a lot better now. It felt like a solid investment.
Reliable gear, consistent service
I've bought from Aces EFI a few times now, mainly for my race car projects. This last order was for a BlackJack Pro EFI system and some Ignition Coils. Just like before, everything was packed well and arrived on time, took about a week to get to my shop. Their products have always been reliable for me, which is why I keep coming back instead of trying other brands. I had a quick question about the wiring harness for the BlackJack Pro, and their tech support was helpful, just like last time I called about a Fuel Pressure Regulator. They've been pretty consistent in terms of product quality and customer service.

Hey, thinking about grabbing one of their EFI kits, probably the Jackpot. How long does shipping usually take to like, California? Don't want my project car sitting around forever.
