AEM Water/Meth Injection V3 Injector & Swirl Generator Kit

Replacement V3 Water/Methanol Injectors (Qty 2), Includes Interchangeable Swirl Generators for 250cc, 500cc, & 1000cc of flow for each injector.

AEM has updated its petrol and turbo Diesel Water/Methanol Injection systems again, this time with a breakthrough injector design that improves atomization to deliver faster inlet temp cooling and use less fluid to maintain cooling. This dramatic improvement in injector technology is coupled with a new WMI pump design that is 100% waterproof, making it safe for engine bay and frame rail mounting. The V3 injector replaces the old V2 injector in all of AEM’s WMI systems and it can be purchased as an upgrade to existing systems.

In testing at AEM, the new V3 250cc WMI nozzle and the V2 250cc WMI nozzle both achieved a 90-degree inlet temp reduction; however, the V3 nozzle design achieved this reduction nearly 6.5 seconds faster. Think about 6.5 seconds in a racing environment.

We then tested a V3 250cc injector against a V2 500cc injector to see if the larger V2 injector would improve cooling speed. The V2 500cc injector achieved nearly identical cooling speed as the V3 250cc injector, but it required almost 44% more fluid to achieve the same cooling. Less fluid used means fewer refills of your WMI tank and less money spent regilling it.

Amazing Spark plugs
Smooth starting came after I fitted these Bosch 9614 double iridium plugs into my 2014 Honda Accord Sport, along with slightly better idling behavior. Longevity might come from those fine iridium tips; installing them felt straightforward enough. Yet here's the catch - the 9614 doesn't match what the factory actually specifies for the 2.4L engine in that year’s Accord. Most often, it's the 9694 or some other OEM-recommended plug you’d want instead

Great plug
Not sure about gas mileage, but these definitely improved the performance of my little 1.8 L Honda Civic, not sure if it’s because the old Plex were just old and weak or just because these are that much better. Acceleration is much better and engine or idle is much smoother
