    Great video Scotty! I used to work at autozone and half the time my coworkers had no clue about spark plugs so they would just recommend the most expensive ones and then customers come back pissed off finding out their cars run worse than their used set of plugs😅😅

    I compared several spark plugs for my 05 GMC Sierra before choosing the spark plugs I put in my truck 4-6 years ago. NGK ir plugs... look like they will never go out of gap. My AC delco oem spark plugs look so cheap & they are & Bosch ir fusions were low endurance crap on my truck. Good advice 👍 Compare the length of old plugs to new plugs before your install

    Which is better sir ngk Iridium or brisk silver sparkplug?

    I use NGK split fires because they are cheap. They are only supposed to last about 20,000 miles but I like to pull my plugs about every other oil change so that I can inspect them and see how things are going. About 1/3 to 1/4 the price of iridium plugs.

    My VW Scirocco 16v had special Bosch spark plugs with three electrodes. They made a huge difference in performance on the car. You had to go to the VW dealer to get them. The other car I had with special plugs was a Alfa Romeo GTV6 which had Lodge plugs. They lasted forever but they had a strange electrode arrangement of four electrodes around the middle conductor so they were flat. They had a silver electrode. Both plugs were good for over 100k miles and this was the 80's. Neither would foul either.

    Aye ain't suppose to improve if not of manufacturing cost also? Thanks for the advice, maybe the time of change and the material not to worn out to maintain the blue-worth spark for electricity side and the smoke not to be produced is observed for best engine performance

    Thanks for the info!Here's over question though:my ex had a Mitsubishi Lancer X, l don't remember the engine model but it was a 2.0 liter 150 hp/ appr. 200N/m torque with a CVT transmission, and l had a Toyota avensis 250 with the 1az-fse D4 engine, 2.0 liter, 147 hp, appr. 200 Nm torque. Both had iridium spark plugs only hers required NGK and mine Denso, and one used a single wire and the other (l don't remember which) had 4 wires.Now the technicians said that:1) Denso was better than NGK any day;4) you can't replace a 4 wire spark plug with a 1 wire spark plug, which l can understand, and that you shouldn't do the opposite as well.Is this right?

    I put Denso iridium TT plugs in EVERYTHING! I first tried them in a s-10. I replaced the original plugs with Bosch platinum plugs and lost a few MPGs. I switch to the Densos and gained 3mpgs over baseline. Sold for life. I have them in a new Corolla that I have achieved 42mpg city with!!!!!

    I put Bosch Platinum +4 plugs in my 3-cylinder Geo Metro and got 14% better mileage for 10,000 miles. Then my son got his license and wanted to show me how to make it accelerate. Soon I had no car.

    I love your videos man! I don't watch any but yours if it involves car stuff that I need answers to. I'd love to sit with a 6 pack and just talk cars and the stupid things ppl do to them lol. Like that Lexus with all the modifications on it that tripped 100 different OBD codes lmao. I had tears rolling from laughing so hard, especially the little pics in the corner, omg too funny. Keep up the amazing work and keep them videos coming!! Much love from Wisconsin!
