A C. C Cronk manager of the Battery Charging station station station sta sta- tion 33 East Fourth South street that he has obtained the exclusive distribution distribution distribution tion of Herz spark plugs in Utah and southern Idaho This famous plug has been a favorite for more than twenty-six twenty years and has been used more than any other make makein in racing cars and machines entered in endurance and reliability tests During During During Dur Dur- ing the war it was practically Impossible to get the famous plugs owing to in inability inability in- in ability of ot the makers to obtain the necessary necessary necessary essary materials in this country EATS SOOT SPITS OIL The Herz has 1 long ng been known as the plug that eats the soot Boot and spits the oil It is absolutely gas tight and cannot carbonize Speaking of the Herz Mr Cronk said The Thel Herz plug Is scientifically correct and mechanically perfect It is covered by an absolute guarantee of quality With the Herz pl plug g the vital spark of your engine needs no doctoring the cloverleaf electrode needs no cleaning for It cannot cannot cannot can can- not carbonize There is no porcelain core to crack but Instead a mineralized mineralized mica mica core so constructed as to be oil and heat heat- proof There is no leaking of 01 com compression compres compres- pres- pres sion slon in Herz cons construction I PUNCH AND PEP PEP The Herz plug performs its work worle unfailingly unfailingly un un- failingly and with the greatest punch and pep It Ignites the mixture in the with a shooting flame that fires every atom of gas producing the maximum driving driving- force without waste of ot fuel tuel or clogging of ot cylinders from carbon carbon carbon car car- bon d deposits The Herz plug economizes gaso gasoline ine I consumption and Increases mileage It I renders cons constant ant valve grinding unnecessary unnecessary I sary and prolongs the life of the engine and its cylinder parts B BUILT IL T BY EXPERTS The Herz plug Is built by expert engineers en engineers en- en and pronounced by the greatest automobile authorities to be the tin finest est estand and most reliable spark plug made inthis in inthis inthis this or any other country The design of the Herz plug constitutes a complete departure from common spark plug conI construction construction con con- I which Is almost invariably govI governed governed gov gov- by price alone I CORE UNBREAKABLE The mineralized mica core Is guaranteed guaranteed guaranteed guaran guaran- teed unbreaKable and soot- soot burning It excels all others for Insulating insulating lating properties Porcelain cores are unsatisfactory Because because because Be be- cause or ot of their liability to crack under heat expansion or from an accidental blow The electrode center to minimize expansion Is too small for tor proper transmIssion transmission transmission trans trans- mission of electric current THIS ONE CANT CAN'T LEAK There is an present ever-present leak leak a a loss of ot compression around the core of ot porcelain porcelain lain plugs Th The Herz plug cannot leak the the very principle of its construction effectually prevents this Pressure from the internal explosion only forces the mica tighter Into the steel shell |
