Claim 8

The reinforced boot of claim 5, wherein said predetermined truncation location of said rigid shell is substantially adjacent where said spark plug cable terminal connects with said spark plug.

Claim 9

The reinforced boot of claim 5, further comprising: a plurality of ribs provided on the other end of said elastomer boot, said plurality of ribs being axially aligned parallel with said central bore; and a plurality of grooves on the inside surface of said rigid shell and axially aligned parallel with said central bore, said plurality of axially aligned ribs and said plurality of axially aligned grooves being in a mutually interlocking relationship.

Claim 10

The reinforced boot of claim 7, further comprising: a plurality of retainer nibs on said other end of said elastomer boot; and a plurality of retainer apertures in said rigid shell, said plurality of retainer nibs and said plurality of retainer apertures being in a mutually interlocking relationship.

Claim 11

The reinforced boot of claim 8, wherein said predetermined truncation location of said rigid shell is substantially adjacent said plurality of ribs on said elastomer boot.

Claim 12

The reinforced boot of claim 8, wherein said predetermined truncation location of said rigid shell is co-extensive with said plurality of ribs on said elastomer boot and said rigid shell has a plurality of slots at one end for receiving said plurality of ribs.

Claim 13

A reinforced boot for a spark plug cable and for a spark plug cable terminal connected electrically and mechanically to said spark plug cable terminal, comprising: an elastomer boot having at one end a flange, said elastomer boot further having a central bore, said central bore having a first portion structured to receive a spark plug cable terminal and a predetermined portion of a spark plug cable, said central bore further having a second portion structured to receive a spark plug; a rigid shell circumscribing at least a portion of said elastomer boot for giving columnar strength to said elastomer boot, said rigid shell having at one end a cup structured to surround said flange on said elastomer boot, said rigid shell being truncated at its other end at a predetermined location along said elastomer boot; a cap removably attached to said cup, said cap and said cup trapping said flange therebetween, said cap having an aperture concentric with said central bore; means for attaching said cap to said cup; and said spark plug cable being received by said aperture in said cap, said spark plug cable terminal and said predetermined portion of said spark plug cable being received by said first portion of said central bore, said spark plug cable terminating within said central bore in said spark plug cable terminal, said second portion of said central bore being structured to permit said spark plug to enter said central bore and electrically connect with said spark plug cable terminal.
