worked for nissan and honda as a tech and i will always recommend ngk laser iridium spark plugs. use them in my own vehicles and perform well
Replaced the torch with NGK BP7ES. Non resistor and run exclusively on propane. All I can say is my WGen 11500 starts every time on the first or second turnover. Torch it would go anywhere between 4 and 7 before cranking. I just know Torch plug sucks.
Swapped the spark plugs w new OEM NGK ones and 0 misfires 0 errors and car runs like new. espeacially notice a difference on start up and idles smoother
My WEN, brand new out the box, would always require a shot of starter spray, take 5 or 6 hearty pulls, and ran rough. Pulled the plug and the stock is a Torch!!! I installed an NGK and it cranks on the 2nd pull and runs smooth as silk.
Mi primer carro también fue un honda Civic 2005, lo tuve como 10 años, esos carros son fieles. Mi recomendación, primero hacele servicio mayor, lo podes llevar a una aceitera y que te cambien el aceite del motor, de la caja, ellos te ponen un sticker para saber cuándo hacer el próximo cambio de aceite, normalmente son como 2500 millas, cámbiale su filtro de aceite, de aire de motor, de aire de la cabina, las bujías, con las bujías el mío corría mejor con las ngk que con las Bosch que suelen poner en todos lados.
used the laser iridium NGK spark plugs. No issues!!
I've had perfectly fine luck with aftermarket coils, 4 years 2 cars no faults. I'm running factory RS7 plugs, I forget if they were NGK or Denso, but they are 1 heat range colder. Working fine with stage 2.
We bought a 2015 Mazda CX-5 that has 155K miles on it. Plugs never changed by prior owner. It was giving us **26 MPG**. The engine was rough at idle. So I read and read about Spark Plugs and purchased NGK LKAR7AHX-S Spark Plug NGK Ruthenium HX Spark Plug that this is better then the OEM ILKAR7L11. So we installed the HX, we noticed the engine smoother but the MPG dropped down to **24 MPG consistently.
BEWARE O’REILLY’S AUTO PARTS CHAMPION SPARK PLUGS ARE WEAK AND BREAK AT THREADS AFTER HAND TIGHTENING AND THEN TIGHTENING NOT EVEN A QUARTER INCH OF A TURN, WAY BEFORE THE TORQUE SPEC AND THEY TWIST RIGHT OFF N BREAK.
Like everyone has mentioned just go back with an ac delco plug. I ran champions and had Mis fires, none of them were gapped right out of the box.
