NGK 6619 Iridium Spark Plugs LFR6AIX-11-6 Pack | Replaces 12565996 MZ602091 BY481-LFR6A SAB330NG4611 4704 5344 5618 IKH20 VKH20 IKH20TT 9613 9615 FR7N1133X 9775.

After being told that my poorly running Yamaha F250 was not worth fixing and I needed a new motor, by a reputable dealer>>>> I went trouble shooting "old school" and found a spark plug issue. So I figured for $50 bucks instead of $30k it was worth a gamble. The boat has never run better !!!! What haunts me is the question about authenticity of the plugs... The plugs and the boxes all looked real to me but maybe I am paranoid. If it walks like a duck and quacks like a duck, is it really a duck ??? LOL

2007 Toyota FJ Cruiser. LFR6AIX-11 (stock number 6619). NGK makes truly great products and the result is many fake products are on the market. I sent pictures of the plugs to NGK for authentication and the reply was positive. NGK corporate is really good about taking the time to help you, they are very nice with very quick replies. Overstock Direct is an authorized reseller on Amazon, however, the Visit the NGK Store link associated with Overstock Direct has no association with NGK corporate. Having said that, I am happy with the purchase I made. I will post the pictures I sent to NGK. Look at the way the Iridium positive electrode post is shaped. It is cone shaped with a small protruding nipple on its center The numbers are on the plug’s hex base, vivid, deep and clear to read. The lines going around the porcelain top are sharp, vivid and not washed out. Now you know how to spot fake NGK Iridium plugs. I will purchase from Overstock Direct again. Hope this helps.

Got these cause they were cheap NGK Iridium plugs. Please to say these were great quality, especially for the money. Now my 2005 Toyota Avalon Runs smoothly again. And after a few months is still running great with no misfires! Will buy again.

Great OEM quality. It helped me to eliminate the check engine light.

Change my plugs every 100000 miles. These NGK plugs hold up

The plugs look fine but I cannot say for sure if Genuine NGK plugs. But I'd like to believe they are genuine. Can only tell after installing and putting some miles on them.

We replaced the ignition coils and spark plugs on our 2009 Toyota Camry V6. We had to remove the air intake manifold/plenum to get to the coils and plugs on the back of the engine. We replaced the throttle body gasket and intake/plenum manifold gaskets while we were in there. We used these parts for the job: 6 - OEM 90919-a2002 Toyota/Denso ignition coils 6 - NGK 6619 iridium spark plugs 1 - Fel-Pro 61445 throttle body gasket 1 - Fel-Pro 96786 set of 3 plenum gaskets We also installed new hood/bonnet struts since the original ones did not hold 1 - set of hood lift struts #6333

All good

Pre gapped, worked perfectly, between these and coils my random misfire has gone
