No so in the case of the '96 CS Posted by sam96CS [Email] (#852) [Profile/Gallery] (more from sam96CS) on Wed, 16 Sep 2009 08:44:08 In Reply to: Re: One thing not to try..., Street, Wed, 16 Sep 2009 08:02:06 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I have the manual for the '96 CS, and the spec for the 4 cylinder engine is 1.0 mm + 0.1 mm, -0.1 mm. The manual does not say that 1.0 mm is recommended. It gives an acceptable range. Anything between 0.9 mm and 1.1 mm is within spec. In English that is anything between 0.0354" and 0.0433", and the mid point is 0.0394"
Tz, plugs wear rapidly in these engines, and the gap gets wider as it wears. Start with a reliable gauge, preferably the kind that's slightly bigger than a quarter and has graduated thickness around its perimeter. Set the gap at the low end of the range or certainly no higher than the middle of the range. Recheck and adjust at 5,000 mile intervals. The manual says replace every 30,000 miles, and you'll be lucky if your plugs perform well that long. Be happy if you get 15,000 out of a set. Keep your plugs in good shape. You'll be rewarded with good performance, fuel economy, and minimal stress on your O2 sensors and catalytic converter. Don't let anybody talk you into setting the gap at the high end of the range.
Also, if you go to the NGK web site and look around you'll find a page with pictures of used plugs with explanations about what's going on inside the engine based on the plug's condition.
