By "Dex 5" I meant to say Dex VI / Dex 6.

I'm doing a drain and fill for a 2003 Suzuki XL7. I believe it's a 4sp Aisin 03-72LS. It's spec'd for Dex 3. Dex 5 is apparently backwards compatible although lower viscosity. The vehicle in in a very cold climate half the year, - 40c/-40f so a good synthetic would help a lot. Low Viscosity not...

OEM spec plugs are nickle plated standard NGK or DENSO (some engines left factor with 3 of each) and are spec'd to be replaced every 30k. I wanted the Iridium TT because they *should* last 100k-ish. For me it's convenience to not be changing them as often. I fully expect zero performance or...

This supplier is better at $0.68 per plug. Can produce 10,000 a day. These "DENSO JAPAN" plugs are made in Jhejiang China by Yiwu Kaixing E-Business Co. Ltd. Contact "Mr. Alex." BEST QUALITY...

If anyone needs to buy at least 100 spark plugs, these guys offer a great deal. $0.75 per plug! Best Quality! These "ASSEMBLED IN USA" plugs are made in Guongdong China, and can ship today...

I contacted Denso USA. They say there's nothing that they can do to help me with determining authenticity. They said try buying from an authorized dealer, which RA is not, ( but where they shipped from is the same address as an auto parts supplier that is). They said Canadian Tire is an...

These are the CT bought plugs. They generally look better, center electrode straighter (but not as good as I’d expect) and more obvious blue colour.

These are RA bought plugs. The pic of the single plug is probably the worst of the lot, center electrode is the most crooked

I’ve bought 6 plugs, same part #, from Canadian Tire, which is an authorized dealer. They have different codes stamped on them but after looking closely, I’m second guessing if the Rock Auto purchase ones are possibly genuine. They look quite similar, possibly from same production line but...

My diesel oil turns jet black about 2 seconds of run time after a fresh oil change. It means nothing, has zero effect on lubrication. If your engine is so sludged that the valves are ticking due to blockages and low oil pressure, sure, maybe you need to clean/flush. That's a whole other...

Brilliant! Shipping label and invoice say: Rock Auto LLC 2782 Eagandale Blvd Eagan MN 55121 A google maps search of that address reveals Factory Motor Parts. DENSO'S website says they are an authorized dealer. Thank you!

What would that look like, where should I look? There are some codes on the box but I don't know how to read them. Box says copyright 2014.

I bought from RA because they're are few options to buy them in my area and I've had good luck with RA before. The main parts store in my area is Canadian Tire. They don't have them in stock, so RA was the choice. I do like the price at RA. They were about $11.33 Canadian per plug all in...

I bought DENSO Iridium TT plugs from RockAuto, part 4704, DENSO part IKH20TT. I am not overly impressed with the quality of them and have doubts about their authenticity. I emailed DENDO and they say RockAuto is not an authorized dealer. Seeing as RockAuto is a reseller, it is possible they have...
