    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😅😅

    4:25 That happened to me and my commodore. I changed the spark plugs which were the OEM plugs and it ran like trash. Removed them and saw the gaps were off even though they had the same part number.. Manufacturing error exchanged them popped the replacement pack plugs in and everything was great.

    I like your channel. I am a hoppy mechanic and a huge Toyota fan .I have had a few problems but it is a vehicle. 95 4 runner bearing race in 5 speed manual cracked. At 150k miles. $1500. repair in 2005. Now has over 500k miles and counting. 2000 tundra broken tooth on planetary gear in automatic transmission . Happened between 100k and 150k don’t remember. 2013 $2000. Repair has 307k on it now.Anything else I have as daily drivers at 200k I spend $500 a month or more just to keep them moving waste of money and time.

    I just changed my spark plugs on my 08 rav-4, which has 210,000 miles. The power and smoothness just got a big boost. I’m probably getting better gas mileage. I gotta check which type of plug I got though, the material i mean

    Had a Buick Terraza with a transverse V6.Took me 5 minutes to change the front 3 plugs.The rear 3? To access them, you had to unbolt the engine mounts and crank the engine forward with a ratchet strap. (They sold a dedicated strap for the job...riiiight)Even still, you had barely enuf room to get your fingers back there.Long story short, took 2 hours to get the rear 3 plugs swapped out and everything put back together...
