The spark plugs on the trdparts4u.com

Is it better to use those ones (iridium) on the trdparts4u.com for Tacoma supercharged or not. Or the K20HR-U11 denso recommended on the technical chat is good enough?

 

So if I understand, don't buy the one on trdparts4u? You know where I can find the ones that are recommended on the technical chat?

 

I believe you are talking about the plugs in the owners manual - Denso K20HR-U11. If so, they are at any Toyota dealership. It's possible you could also source them from mass marketers like O'Reilley's/Auto Zone/etc.

This may not apply to Denso plugs used on 2nd Gen Tacoma's, but I'll bring it up anyway. Some years back I replaced the spark plugs on a 4 cyl Accord with the OEM part # acquired from a mass marketer place like the ones mentioned above. Looked identical to original plug - same part #.

Unfortunately - there was a difference. The terminal(top of plug) on the MacParts plugs had terminals that would screw on and off. Not unusual on some plugs. The dealer plugs had terminals that were affixed. One of the MacParts plugs had a terminal unscrew itself from engine vibration. Plug wire came off at a stop light.

If not sourced from a dealer, check the terminal end of the plugs and ensure they don't have this problem.

And regarding the NGK plugs mentioned in the owners manual...there would be no problem running these either. Part #

$6 LFR6C11 NGK (7787) LFR6C-11 V-Power Spark Plug, Pack of 1

LFR6C11. I've used both NGK and Denso in many Asian vehicles. I've never been able to detect a difference in performance.

 

Thanks,

Seriously, your advice just arrive at the good moment because I had a shop which sell the same model denso as the original but I prefered to buy it from toyota, I want the real original one.
