Definitely a difference in throttle response and power increase. There were standard single port injectors and the switch is definitely noticeable on the '99 Cherokee. Definitely worth switching.

Installed these injectors while repairing the engine. The engine ran rough so I replaced every sensor I could think of to no avail. Found that one of the injectors is sticking. nothing but cheap junk. Look for Bosch injectors if you want quality.

The product is absolute rubbish. waste of money. Did a complete tuning and changed all injectors. After all, this jeep drove very badly. 3 of 6 scrap found. took them out Went to the nearest auto shop and spent $250 and the jeep drives great.

I think for the price you can't go wrong, just installed them, everything went very smoothly, took less than 25 minutes to complete all six to do. without check engine light. no change in idle power, they seem to run a little faster, much better value than spending $54 on one at AutoZone.

DO NOT BUY! It made my car absolutely horrible. From the first run they worked absolutely terribly. They made my car look like it was backfiring and stalling at 3-4k rpm. I put the OEM injectors in and everything worked fine so it was definitely those crappy injectors. DO NOT BUY! Keep researching and don't make this mistake like me.

First of all it only took me 2 days to get it to my door, it's amazing. The fact that the parts store charges the same price for any of the 6 I have in this kit made a deal I couldn't refuse and I'm glad I didn't. I installed them on my '04 Jeep Grand Cherokee with a 4.0 liter inline 6 engine, I noticed a big difference in the smooth idle and it has much better throttle response. I haven't checked the numbers, but I'm pretty sure I'm moving further down the tank than before, so that helps as…

So far I'm happy with these nozzles. I modified the head to match the headers, added an aftermarket cold air intake, a 2.75" exhaust all the way back, and a new set of caps. Rotor connector and cable. There was one very clear difference. Consistent power up to 4000rpm. In my 1998 2-door XJ, 5-speed. I had to swap out the injector plugs with Power Tech plugs on the donor engine I had. Polarity is important for optimal performance. Some say it doesn't matter, but it really does. Very much value…

Partly my fault I'm not an auto mechanic but bought replacement injectors in July but wasn't able to fit them until December 2020. My son-in-law is my mechanic and his management is primarily father-in-law's family so maintenance has taken a back seat. We pulled out 6 injectors and found 2 cracked factory installed injectors that came off the assembly line (2004 Jeep Wrangler TJ Rubicon 4.0L). The truck had issues that we knew needed service, but it's not my daily driver anymore. After…
