I was wondering, if anything, maybe a better response on acceleration, faster start-up. Changing from a single hole injector to a 4 hole injector probably will reduce mpg a little. I thought they were 2 hole injectors.

 

Interesting how a thread addressing the Bosch remanufactured 4 hole injectors transitioned into a discussion concerning the distributor cap, rotor, contacts, interpretation, etc.

Not being sarcastic, just interesting.

 

i will use them on my van, good price..

 

Probably won't change any MPG noticeably, eureka, as the computer fires 4 injectors at once, Ford calls it multi-port injection. Once the system warms up enough to go closed loop, the O2 sensor in the exhaust will adjust the fuel mix so the MPG will be the same as before.

Where the extra holes are an advantage is spray pattern and not having a single orifice which could clog but multiple holes. Spray pattern is important if sequential EFI is used by hitting the back of an about to open intake valve.

Batch-fire is the term you're looking for..

 

Yep, that's what everyone calls it except Ford. They have CFI, MFI, EFI, SEFI, and probably some I missed.

I am going to purchase them. Great price considering everyone else's price. Ebay seller has been around since 2004. 100% positive rating. I have contacted him with some questions. He was very responsive and knowledgeable. Along with the 5yr. Warranty, seems worth a try.
