Beru Plug Gap

Recommended Posts

Four hours and 20 minutes later, the plugs are in. The plugs made a HUGE difference. There was a measurable response in the throttle. (Changed the oil yesterday to Castrol 5W 40 synth. My filter is leaking a bit. Need to order a filter tool from Suncoast.) In fact, with the change in plugs, the ticking (coming from the exhaust manifold-driver's side) I reported in another post has quieted down to the point where it can barely be heard. I took pictures of the old plugs and hope to upload them with another post in the future. What I found interesting was how worn the old plugs were. When comparing the new and old, the old plugs had the center pin worn to an oblong shape, but very thin in width. The "arms" that reach to the center pin were 1/8 shorter (on each arm) when compared to the new plug. Can any one estimate how many miles are on my old plugs in this described condition? The color of the plugs were silver grey with lite brown spots mixed in over the center pin and arms. No oil on the threads or any areas of moist black soot

There is a lot to be said for torque spec. I noticed on my 99 Box when replacing the plugs, the specs were erratic at best. Each plug had a different torque spec number, the coil pack's upper bolts were tighter than the bottom, and the oil filter case was so tight I used a 911 open-end oil filter wrench to loosen the case to spin off. With the plugs and coils all properly torqued, and the new plugs themselves, all combined to improve the car's performance in a big way, I believe.

Thanks to Loren and RennTech Members for your advice and support. You gave me the confidence to DYI!
