Review on Optimize your vehicle's performance with the Denso 234-4169 Oxygen Sensor by Bob Trapp

After 15 years and 131,000 miles on my 2000 Tundra 4x4, the 4.7 liter check engine light came on for the first time and I was told that one of my oxygen sensors needed to be replaced. I replaced all 4 myself with no problem. 2 downstream: Denso 234-4162. All 4 are identical to OEM except for the cable lengths. Each OEM has different wire harness lengths and they were all slightly shorter by 2-2.5 inches compared to the replacement, but the price is about 2/3 lower than even a discount online retailer so there is no point in asking the retailer to make richer. he already owns. Right? I was concerned that the longer wires would rub against the 2 new sensors on the engine/transmission so I also bought an Allstar Performance ALL76600 1/4" coiled wire harness and it did a great job protecting the wires. I'm very glad that I found this sensor at a much lower price here at Revain These were the online retailer prices AFTER the 20% discount: Front Left 89465-09310, $116.99 Front Right 89465-09190, $132.95 89465-34140 Rear Left, $145.10 Rear Right 89465-34150, $145.10
