There is no point in paying Honda an insane premium for parts which they clearly source from someone else. Of course, I’m old enough to think that even 18 bucks for a spark plug is highway robbery:-)<br><br><div dir="ltr"><span style="background-color: rgba(255, 255, 255, 0);">Tom Coradeschi</span><div><span dir="ltr" style="background-color: rgba(255, 255, 255, 0);">tjcora@icloud.com</span></div></div><div dir="ltr"><br><blockquote type="cite">On Oct 21, 2021, at 7:42 PM, Jim Stone <1789alpine@gmail.com> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">My 2017 Honda Ridgeline is approaching its 105,000 mile service, which is a big one. New timing belt is the main event, but Honda also recommends new spark plugs. I did the timing belt on my old Ridgeline at 220,000 (it’s 3rd belt) but it was a PITA and I don’t think I want to take any chances on a newer, more valuable vehicle. Spark plugs are a different story and the dealer gets over $300 to do those!<div class=""><br class=""></div><div class="">The reason changing plugs is so expensive is Honda’s price for the plugs themselves. They list at $55 <u class="">each</u>, although you can get them discounted for the low, low price of about $40 each if you shop around. <a href="https://www.hondapartsconnection.com/oem-parts/honda-spark-plug-dilzkr7b11g-ngk-12290r9pa01" class="">https://www.hondapartsconnection.com/oem-parts/honda-spark-plug-dilzkr7b11g-ngk-12290r9pa01</a> But, here is where it gets interesting: The owner’s manual lists the plugs as NGK DILZKR7B11G, a number you can clearly see on the Honda box in the above link. NGK lists that plug as $18 each (<a href="https://www.ngk.com/ngk-95350-dilzkr7b11g-laser-iridium-spark-plug" class="">https://www.ngk.com/ngk-95350-dilzkr7b11g-laser-iridium-spark-plug</a>) and you can find them at Rock Auto for about $12.</div><div class=""><br class=""></div><div class="">Ridgeline owners seem to be divided as to whether the plugs in the NGK box are any different from the ones in the Honda box. I trust this group more than fellow Ridgeline owners. What do you guys say? Are the plugs in the Honda box likely to be different and worth an extra $170?</div><div class=""><br class=""></div><div class="">Jim</div><span>_______________________________________________</span><br><span></span><br><span>Shop-talk@autox.team.net</span><br><span>Donate: http://www.team.net/donate.html</span><br><span>Suggested annual donation $12.96</span><br><span>Archive: http://www.team.net/pipermail/shop-talk http://autox.team.net/archive</span><br><span></span><br><span>Unsubscribe/Manage: http://autox.team.net/mailman/options/shop-talk/tjcora@icloud.com</span><br><span></span><br></div></blockquote></body></html>
