Denso(3194) K16TR11 Spark Plugs, Pack of 6

Good quality

they work great and you can't beat Denso quality for you 5vz motor

Great brand at a great price, shipped fast and I got my parts when I needed them. Would definitely recommend them to anyone and I definitely will be ordering from them again.

2003 Tacoma 3.4 v6 worked like new

Just completed timing belt, wp and tune up on my 2001 4 Runner, with 247k. Ordered a kit from TRQ which included plug wires, plugs and coils. My last complete tune up was done May 2013, with 161k miles, by my local Toyota dealership where I purchased it from.I have several cars, so my 4 Runner is not driven much. The old coils still looked great as did the plug wires and plugs. A photo showing the old plugs is attached. They were NGK instead of Denso which was odd since the dealer performed the work. As you can see, everything is still looking great. Even the plugs with over 80k looked almost perfect. The gap was 36 instead of 44 which I thought was below spec. Even so, she ran perfect, with no misfires or even electrode wear. Very unusual. I ended up just replacing these plugs, since the plugs in the TRQ kit were single electrode, platinum. The only issue with the Denso was that they were not pre-gapped. Some were 34,38 and 40. Make sure you check gap.

Don't expect plugs to be at $5 each. one failed in less than a year. I purchased this in Jan 2024 one failed in Dec same year. Misfire code popes up. I replaced the bad plug with the old one that I kept and the misfire went away. the original Denso is more than $10 each maybe around $15. not worth the money. you will damage the engine

Fits 1999 Toyota 4runner

These have been my go to plug for my 4runner. OE part and great performance.
