I'd ordered these Deno fuel injectors second hand from Japan a little while back, and thought it might be a good idea to get them checked out. So today I went to a shop, but I ended up doing a full write up on everything you could ever want to know about fuel injectors!

Whats inside, how they work, cleaning, balancing and flow testing, all explained in great detail in this article I wrote up: The Skylife: Fuel Injector Flow Testing: Cleaning and Balancing Exlpained

I figured pretty much everyone would appreciate a little extra knowledge on the subject, I know I sure learnt a lot today! I also made a video (posted in the article) that shows the whole process start to finish.

This is the testing rig, all wired up...

and this is the cleaning process....

It was pretty cool to see how the injectors actually spray, how quick they work, and holy god how much volume they can move in a matter of seconds!

It was an excellent experience, that really had some definitive, conclusive results.... meaning... we tested them for a baseline, cleaned them and then re-tested them and the results were pretty impressive! I'd say injector cleaning and balancing is one of those things for second hand injectors, or even just old injectors that will make a world of difference. Hope you guys like it and find it marginally interesting lol...

hey there, it cose me about $35 each injector...

so you can see that really if you had one leaky injector it would be an incredibly effecient quick fix, but doing all six is a little costly, but then again, its somewhat essential for second hand injectors, considering I got these at a fairly reduced rate (less than half the price of new)... so it works out to being a little cheaper than buying new. for some I'd see it as worth it to just buy brand new, but for others that may not be an option

The price isn't that bad for a four banger though; Damn six cylinders haha
