NGK 6619 Iridium Spark Plugs LFR6AIX-11-6 PCSNEW

Work great! The gap was accurate and consistent for all 6 plugs.

NGK LFR6AIX-11 approximately every two year, I installed these on my 2006 BMW 325XI with the N52 six-cylinder engine. The car has 123000 miles, runs great and for $50 every two years it is an easy way to help keep an older car running smooth.

Reliable and smooth. Makes my old car run like new again. I only use NGK spark plugs in my Hondas.

I got the same spark plugs a couple of years ago, but I had to replace them now...... So I wonder how long do they really last?

Works good

These plugs worked great in my 2005 Tacoma 4.0L V6. I had 76,000 miles on the original plugs and they were way overdue for a change out. The Iridium plugs won't make your engine run better than the original OEM plugs, but, they will last longer. Of course, in my case, the plug change made a noticeable difference because my truck was misfiring at idle and not burning the fuel cleanly (you could smell the exhaust in the garage). The plug gap on this engine calls for .044 and the OEM plugs looked to be about .055 when I pulled them out from the wear. The new Iridium plugs are pre-gapped at .043 and I left them there with no problem (always better to have plugs gapped a little tighter since they will open up over time).Here are some tips for changing out the plugs on the Tacoma V6 engine (there are good YouTubes on this as well):1. Remove the engine cover (two 10mm bolts).2. Passenger Side: remove the air cleaner (two 12mm bolts and loosen the 10mm hose clamp).3. Driver Side: take a pic first just in case and then remove the vertical bracket (two 12mm bolts) that's in your way, the vacuum lines, electrical connections, that will be in your way as well. It looks hairy, but, take your time and it will only take a few minutes to save a good bit of frustration.4. On all 6 cylinders, remove the electrical connectors and 10mm bolt holding the boot into place and remove the boot.5. Using electrical tape, secure a 5/8" spark plug socket to a long 3/8" extension.6. Carefully and slowly remove each of the 6 spark plugs.7. Carefully install the new plugs making sure not to crush the gap and not cross thread (just make sure to hand thread them as far as possible). Snug them up until they bottom-out, then only torque to about 10-15 foot lbs (about a 1/10th of a turn). Some suggest using anti-seize. I didn't but would if I had to do it over again (you don't want your plugs to break when removing them the next time). Don't use grease on the threads (this will impact the torque and could cause the plugs to loosen from the engine vibration).8. Reverse Steps 1-4.The process should take 1.5 hours or so and is fairly easy provided you don't run into any problems like getting your spark plug socket stuck in the cylinder (be sure to secure the extension described in Step 5).
