Bosch Platinum plugs, Slick-50, Mobil 1, and Armor-All !!

[Daniel Burk]

I thought I would interject a little study that I performed on the
standard AC plug, the Bosch Platinum, and the Rapidfire plug by AC.  

I went from a standard AC to the Bosch in 1993 at 65,000 miles, and
picked up 2 MPG; I also replaced teh timing chain at the same time, as
well as the plug wires.  Take it for what it's worth.

I replaced the Bosch plugs at 90,000 miles in 1995 with AC Rapidfires. 
I saw no performance imrovement, even considering the Bosch plugs had
25,000 miles.  The Bosch still look good and I could re-install them.

At 115,000 miles, I noticed that the Rapidfire plugs had the splines
that they advertise burned off them.  I use a Accel supercoil and a
Crane Hi-6 ignition module.  I regapped them and reinstalled them.

At 124,600 miles, the car has begun to miss.  The distributor cap's
brush to rotor interface has burned out it's electrode (Totally turned
to slag!).  The Rapidfire plugs have burned off their electrodes as
well.
I've disconnected the Hi-6 CDI unit.

I plan on buying a new set of the Bosch Platinums, as well as a new coil
and spiral core wires.

Regarding Split Fire plugs and Slick 50:  

I got a tour of Roush Industries in 1995.  

While in the Dyno building, where 15 dyno cells were all running at
wide-open throttle,  I asked the Roush representative if they had ever
tested Slick 50 and/or Split-fire spark plugs.  The rep said yes, they
had extensively tested both products.

Roush industries said that they saw no measureable increase in
performance from either product. 

I underline the word measureable.  The tests (I surmise) pit synthetic
motor oil against Slick 50, and NEW plugs against NEW splitfires.

When I asked which products have they seen positive results from as far
as performance, they said look at Bosch Platinums and a fully synthetic
motor oil like Mobil 1.

I felt good, because I use both.  Probably always will.  

I even have Mobil 1 in my lawn mower.   

One thing I swear by when it comes to performance, is that pure
subjective feeling that my car runs better when it's washed and the
tire's sidewalls are armour-all'ed!
