Zato 😁 Spark-plug length varies because different engines and cylinder-head designs require different physical reach, heat management, and sealing characteristics. “Length” usually refers to the threaded portion (reach) and the insulator nose length; both affect fit, combustion and cooling. Key reasons and effects Reach (threaded length) Provides proper spark location relative to the piston and combustion chamber. Correct reach positions the electrode in the optimal combustion zone for flame propagation and avoids impact with valves or piston crowns. Ensures correct sealing with the cylinder head and engagement with the thread depth specified by the manufacturer. Wrong reach can cause exhaust leaks (too short) or physical contact/damage (too long). Insulator nose length (projecting ceramic) Influences heat dissipation and quenching. A longer nose projects further into the combustion chamber and changes the thermal profile of the plug. Changes likelihood of pre-ignition or fouling. Too-hot plugs (insufficient heat-sinking) can cause pre-ignition; too-cold plugs (excessive heat-sinking) foul with deposits. Manufacturers pair nose length with a heat-range rating to manage this. Electrode position and combustion dynamics Electrode location relative to the center of the chamber and incoming fuel/air jet affects ignition quality and flame kernel growth. Some engines (high-compression, direct-injection, or specific combustion-chamber shapes) require one configuration to optimize burn and emissions. Mechanical and service considerations Extended reach may be required for recessed or deep combustion chambers; short reach for shallow or pent-roof heads. Aftermarket performance plugs sometimes use different lengths to accommodate custom heads, turbochargers, or nitrous setups, but proper fitment is critical.

Boljsa eksplozija, boljse izgorevanje. Kar pomeni malenkost boljsa odzivnost in malo manjsa poraba.

Pa da vidimo kok se bojo obnesle svecke z vgrajenim kondenzatorjem 😊

Ameriske z visjo opremo so mele to original Js sm mel sicer z aliexpressa drugo masko in se tega ambilighta ni dalo vgradit, pa sem si led trak namontiral na tak nacin pa mi na tehnicnem nihce bi nic rekel

Drzi 👍🙂

Ups pa res, za cel liter je razlike

Skoda motorja za po omejitvah se vozit? No tist karpa ni po omejitvah pa nebom javno 😂 No sej mestne voznje so pa druga pesem... Ampak v primerjavi z dizlom 2.2 awd je mogoce sam pol litra razlike v prid dizlu.

Koncno mi je uspelo it na mal daljso relacijo po AC in testirat realno porabo pri voznji 130km/h. Dolzina voznje cca. 130km. Ni slabo za 2.5 benz 😊

Zmontiral nastavke 🙂

Da bomo bolj stabilni 😁

Js je ne menjam za nic, res je vrhunski avto! 🙂

Se pravi, da je tudi olje ostalo enako?

V novi M3 je se vedno enak avtomatski menjalnik?

Je ze ni vec 🙂

Moje najslabse kadarkoli sem jih mel so ble pa Kormoran 🫣 Pirelli Powergy XL 118€ po gumi 🙂

Letni komplet zmontiran 🙂

Ok, sm tole mal brskal, pa ni nobena druga posebnost, kot to, da majo na jezicku se dodan koscek iridija. Bi pa blo zanimivo za sprobat kaksne Pulstar al pa Brisk svecke, ki sta trenutno edina proizvajalca, ki izdelujeta svecke s Pulzno iskro, to pomeni, da je v sami svecki dodan kondenzator, ki sprozi na svecki mnogo vecjo iskro, kar privede do boljsega izgorevanja na cilindru 🙂

Ni res, ene majo bele robove 😋

Je kdo ze preizkusu Rutheniumke? 🙂

Alfa Romeo 🙂
