Overview:
Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49144. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency.
Designed to fit the 2008-2013 Infiniti G37, 2014-2015 Infiniti Q50, and more, this direct-fit catalytic converter also interchanges with OE parts B08B2-1ET0B, B08B2-4GB0B, among others. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Effective
Size: 300 Milliliter
This worked wonders on my car’s performance! After one use, the engine started idling much smoother and the throttle feels more responsive. A very high-quality German-made product.

Great for All Cars but Especially German Cars
Size: 300 Milliliter
I use this in our used VW we bought and it helps keep the carbon build up down with their direct injection feature. I pair it with their oil additive which helps lubricate the rings so they don't stick as much.

Significant Improvement in Performance with Liqui Moly Jectron
Size: 300 Milliliter
I've been using the Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner in my vehicle, and I am thoroughly impressed with the results. The 300 ml bottle, though compact, has made a noticeable difference in the performance of my car.
After adding the Jectron cleaner to my gasoline tank, I noticed an improvement in the engine's responsiveness and smoothness within just a few drives. The idling has become steadier, and the acceleration feels more robust and refined. It's as if my car has regained a level of vitality that I hadn't realized was missing.
The cleaner is incredibly easy to use – simply pouring it into the fuel tank before filling up ensures it mixes well and distributes evenly throughout the fuel system. I appreciate that this product is designed to be compatible with all gasoline engines, making it a versatile choice for different types of vehicles.
One of the most significant benefits I've observed is the reduction in start-up problems and engine hesitation. It's clear that the Jectron cleaner effectively cleans the fuel injectors, improving fuel atomization and combustion efficiency. This has not only enhanced the driving experience but also contributed to better fuel economy, which is a fantastic bonus given current fuel prices.
The blue color of the liquid and the design of the bottle make it easy to identify and use, ensuring I don't mix it up with other products. Despite being a single 10.14 Fl Oz pack, this cleaner packs a punch, proving that a little goes a long way.
In conclusion, the Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner has exceeded my expectations. It has revitalized my car's engine, improved fuel efficiency, and provided a smoother, more enjoyable driving experience. I highly recommend this product to anyone looking to enhance their vehicle's performance and maintain the health of their fuel injection system.

Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order.
I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work.
Likes:
Amazon Prime shipping, returns and refunds within 30 days of receipt.
Reputable product.
The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can).
Comes with dispensing attachment for easier pouring.
Dislikes:
The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside.
Meh:
I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps.
Hopefully this honest review helps someone decide about this product.
