Just thought I would give a little feedback. My injectors were original out of an '87 951 which ran/runs great but needed a lot of TLC and I've broken it down. Sent these to witchhunter.com and they came back looking like new. I personally didn't see much improvement because German engineering in '87 has perservered through the past 25 years of this car... I'm very happy with keeping the original bosch (which has a superior pattern than many of the new ones) and what witchhunter did for 21 bucks a pop.

WitchHunter does a great job. Consider spraying the body of the injectors (the silver part) with a clear coat or some kind of paint or they will rust.

I was going to send out the injectors on my '00 Cherokee to be cleaned, 125k miles on them and they are original. Thing is stuff for this thing is so cheap that at $21 an injector its basically the same price for me to buy 6 new injectors.. .

Just wondering why do you think that #4 needs the most fuel? Thanks.

I think #4 tends to run a little hotter maybe because of water flow issue therefore it is a common location for HG failure. Therefore running a tad richer on that cylinder keeps things cooler and reduces probability for destructive knock.

You tend to see higher egt's at the number 4 cylinder.
