Are my injectors stock? PIX

[beyondstock]

Ive been having problems with tuning my car. Maybe because I bought the car with half the crap installed and have that was supposed to be on the car was BS. I just pulled these injectors out to determine what size they are, as I was taking a stab in the dark at my cc ratings. I'm going to take an educated guess and say they are stock. However, I've heard of using stock injectors but modified. They are like brick red, they have a part number and say DENSO on the side. I can get the part number if needed.

Yeah, get the part number and you will probably be able to find what size they are by a simple google search.

What engine?

Don't look like stock DOHC KA or SR or RB25 injectors.

well hell, you are right! Google says Sard 550cc... Now Is there a way I could clean these myself? just to make sure they are working properly? Or will I have to send them off for cleaning?
