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: http://tinyurl.com/474p88k

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...

The sight of a Nissan injector makes me cringe. I have not so fond memories of working on the Maxima and both of my Q45s in the sweltering heat, trying to replace those tedious little things without breaking the brittle plastic.

Also, cool article

6 months ago, at 278k miles, I replaced my VG Maxima's first fuel injector. It was a much, much simpler job than I expected it to be.
