Happy guy
Once again zzp you guy and the amazing things you do. The injectors where totally plug and play...My tuner out here in Myrtle Beach SC was amazed by all of my ZZP upgrades..I just want to say thanks again.O yeah my 13 Buick Regal with the stock block and heads, only ZZP upgrades im making 320 to the wheel...Lets Go

Opal HP Direct Injectors
Super simple and easy removal and install. Literally plug and play. The people at ZZP are very knowledgeable, and gave tips to make this project easier.
Just like the Factory
I bought these for my 2011 Buick Regal CXL Turbo 6MT because I had a leaking injector due to it being broken during my engine replacement. I received and OE part that bolts right up. I recommend buying a new fuel rail like this instead of trying to reseal your injectors because you might break the tips off just like I did.

What a big difference on performance
Big job replacing this but at the end a big change on power and performance i feel other car
