It’s a spark plug. All cylinders fire, so I guess they work.

Thank you all for the quick and friendly service to help me with the Plugs. Was really in need of a new set. I will call you if I need any more parts for N32DQ. Have a Great Day. AKA: The Captain Morgan Ret.

consistent timely efficient and correct service everytime

Showed up quickly and in good shape

Should have changed them earlier - 15 years on the old ones, which tested good. Unfortunate that my last overhaul switched to REM from factory RHM, but Im sure someone would like a free set.

Timely delivery as always

This is the sparkplug that was in my grumman cheeta .....I replaced it with same, the engine runs like it has new plugs....starts faster, runs smoother and stronger.

Price was very competitive ( although all aircraft parts are too high!) Items arrived promptly even amidst the wuhan virus

I use Spruce for everything, fast response!!

Well packed, thanks.

Very fast delivery to New Zealand. Goods in excellent condition

Perfect!

quick delivery product as advertised, wonderful company to work with.

Good company to work with.

Easy to shop for, best price and on-time delivery. Quite pleased.

Good purchase, great service.

Nice product and packaged well. Will be buying more.

Champion plugs work well in my Continental 0300

Fixed my 172

Right size , working very well.

Product is of high quality and delivered sealed and ready to install. Price is outrageous and continues to escalate. I thought $15 a piece was awfully high but was astounded with $35. I guess one must pay to play.

All was good even though would/could not accept the return of incorrect plugs as mechanic had opened!

Out of 24 spark plugs three were bad sent them back had to install three old ones

Ordered the wrong part #, my fault but Aircraft Spruce refused to take it back because I opened the package. The plug was never installed. Buyer beware, spark plugs have a different return policy than the companys stated return policy.
