AAA+ Item exactly as described, quantity of 4 blades. Fits Toro Recycler, looks identical to original Toro blade. Nicely wrapped & packed for no damage in shipping. Shipping out next business day. USPS lack of tracking information, only initial out shipping and final local delivery information, took days longer than expected, as USPS issues/ nothing to do with One Time Best Price packaging or label. No issues with whole transaction AAA +

This feedback could have gone either way. Unfortunately all 3 copies I ordered of this record arrived badly damaged due to insufficient packaging, but the seller promptly apologized, said that they will learn from the mistske and ship vinyl more securely moving forward, and refunded me with no questions asked. Thanks to the seller for making a bad situation better. Thank you for making the process painless.

Package lost in shipping since mid march. Seller refunded money shortly after realizing package had been missing. Package did show up 5-16-25. Seller advised me to keep package. Only reason I gave 5 stars on shipping is to not give seller negative feedback. Would highly recommend this seller.

Be prepared to regap these, otherwise fine.
These spark plugs deserve four stars because they appear to be top of the line, genuine Denso spark plugs, but the gaps are wrong so they need work. Despite the star rating caption, they are not so good as I expected. Gaps ranged from .024" to .054", and none of them was close enough to the specified value of .044" to be usable without correcting the gap. One also had the Iridium points a bit misaligned which needed to be adjusted. It might be reasonable to assume that these were factory rejects. I still think they are good value for people that don't mind correcting the gaps, and saving about ten dollars per plug.

They work as they should with some tweaking
The Good: The car runs great with the new plugs. The Not so Good: I had to re-gap all of them. They came gapped to .028" These are the identical plugs as what I removed. The gap spec for my vehicle is .044" and I was expecting them to be properly gapped out of the box. In general, it's not a good idea to gap iridium plugs since it may damage or snap the fragile tips off. The Bad: 2 out of 6 new plugs had a sharp barb of arc weld residue where the ground electrode attaches to the thread body. I had to carefully remove it with a jewelers file under a magnifying glass, and retrieve metal bits that lodged between the ceramic and thread body. Maybe these plugs were re-boxed knock-offs or the batch slipped thru normal QA inspection. The Good: The car runs great with the new plugs. The Not so Good: I had to re-gap all of them.

Awesome Spark Plugs
I'm so glad I bought these OEM Spark Plugs for my 06 Toyota RAV4 with the 3.5L V6. Honestly, I haven't changed the spark plugs at all and after over 161,000 miles, I finally did. What a difference! I could tell right away. These Denso spark plugs are amazing and the price I bought it from the seller was great. For anyone who owns a Toyota that has these plugs, I highly recommend replacing them with the same. I'm so glad I bought these OEM Spark Plugs for my 06 Toyota RAV4 with the 3.5L V6.

Suspect counter-fitted parts, don't buy these.
This is highly suspected counter-fitted parts. Out of my suspicion, I measured the resistance on these plugs, 3 of them shows 5.1x KOhms (which is normal (ish), and out the the other 3, 2 shows 3.1x KOhms, and one shows 4.2x KOhms. If they are genuine parts, they CANNOT be this in-consistent.

Terrible Quality
For the price, I should have known it was TOO GOOD TO BE TRUE. I had not yet opened the package of plugs that I had received. However, after reading numerous poor reviews, I figured I better check them. Sure enough, I only had to compare 2 of the 6 to clearly see the gapping was terrible. It wasn't even close in comparison. With what it takes to replace the rear plugs in a RX-350, there is absolutely no way I would consider installing this product. Not sure if I was still in the window of return, but not wanting the hassle, I just threw them in the trash. I would certainly assume they are a counterfeit product. Lesson learned. I'll end up paying almost 2x as much but will end up ordering them from Rock Auto. For the price, I should have known it was TOO GOOD TO BE TRUE.
