Can blueprinting old fuel injectors really increase performance? | Articles

Ooh! Good reminder – I have two sets of injectors I need to send in!

Anyone know the differences between RC and witch hunter? Better? Worse? 

How does this compare to buying new injectors from rockauto etc? Is rebuilding a factory set actually better? Or are new aftermarket pieces junk?

Yes!  I sent my OE ND injectors from my FC to RC, and they fixed them up ASAP.  That fixed my hot restart problem.  Highly recommended!

In reply to freetors :

“New” injectors from rockauto are going to be cheap turds that fizzle out. OEM injectors are the business, it’s why you pay so much for even reman OEM injectors. 

Besides the obvious quality difference, it’s also way cheaper to have RC rebuild injectors than it is to buy new. RC charges about $25/each, but RockAuto injectors are about $50/each for this car. 

New injectors will not get you a matched set, this is very important for getting the same squirt in each cylinder.

How often should this be done, 100k, 200k? Is it worth looking at the tune after this too?
