S3 Injectors

So in preparation for my 2+ unitronic tune (and later jhm tune.) I'm trying to get the s3 injectors into the car. Are they a direct replacement or will I need some sort of fittings or something?

Direct replacement. Just make sure you get a new instal clips because they tend to break

As an aside, you won't need S3 injectors for either of those tunes. I currently run the JH M stage 2, 93 octane tune, and have S3 injectors, but the tune doesn't take advantage of them. The only time you're going to need bigger injectors is if you're going to a larger turbo.

Good to know, will order the clips tonight. And the unitronic days they're required so I did it for good measure lol

Dont waste your $$$$$ on S3 injectors unless your KO4 or bigger. I dont know of any tune less then KO4 that utilize them

It is for a K04 swap

Then you will need to S3 injectors or RS4. Most people prefer S3 for trouble free cold starts in winter mornings

The clips are interchangeable between stock, s3, and rs4 injectors.

Did you purchase them new. If you did they already have new clips. If used and a few are broken just re-use your old one from the stock injectors if you dont break them. Most time the O rings are re-usable also
