Just an FYI, InjectorsDirect doesn’t have a very good reputation, because of selling crap in the past. Hopefully you won’t have any issues with them.

Yes. The cp4 is timed. The cp3 is not.

Does the CP4 trash the 9th injector also? I’m assuming yes. Only low pressure item I have not flushed.

Okay, just to confirm, you replaced the CP4 with a new CP4 or the CP3?

CP4.2. 2 year warranty. The CP3 kit was twice as much. Couldn’t justify it when my truck has 190k miles. Figured the kit I bought would get me another 190k. I have a lift pump and now running opti-lube.
