These are good plugs however at over $300 each after shipping and tax, I believe that massive electrode plugs are more cost effective if you clean them more frequently. I have been using these fine wire plugs since 2016 and havent experienced a big enough difference to justify the price.

One of the best batteries on the market. If you are a piper owner, please read the STC list carefully, older cherokees ned the RG-35, newer cherokees use the RG-25. Dont get this confused or you will make costly mistake that is not Aircraft Spruces fault.

I ordered this battery because it was the only group 35 in stock. I paid more than the Gill but this really spins the prop on start. Installation in a Piper required the removal of the wood hold down in the original box but that wasnt a big deal. Hope it lasts a long time.

Ian D Verified Purchase

CONCORDE SEALED BATTERY RG-35AXC

I like Tempest plugs in general as they tend to have better resistance values than Champions. However, the wrenching on tempest plugs are lower on the plug than Champions and this presents a problem when utilizing spark plug gasket CHT probes. There is interference between the wrenching and the wall of the counterbore for the spark plug on Lycoming engines. I have had to utilize a champion plug in that instance.

Great product and service from Spruce! . Made a huge ruin performance. Plane runs smoothly. I replaced REM38E with theses Tempest UTEM40E. CHT doesn’t run hotter like I was concern. Much cheaper the the Champion and does exactly same thing. You pay Champion extra for the bran name.

Romeo T Verified Purchase

My go to plug, Have only had one plug prematurely fail in a decade.

Raymond L Verified Purchase

TEMPEST SPARK PLUG UREM38E

Love this battery. The extra cracking amps made all the difference in my 210K. Before this battery, it struggled to turn over the engine and always required a couple bumps to get it past the first compression stroke. Now it just turns it no problem. Concorde supplied the STC and permission letter on request. Worth the money for sure.

Paul W Verified Purchase

CONCORDE SEALED BATTERY RG-35AXC

The battery is the best. The STC issue is pain. I tried to order from Wilco, but they did not have stock. So Spruce had the battery but no STC. Wilco has the STC but no battery.

I ordered this product as a replacement for my G 25 lead acid battery. I had to return it, it was not a direct replacement. It was 8 pounds heavier, and almost 2 inches longer, and would not fit on the existing battery shelf. other than that, I like the idea of it but unfortunately I was not able to use it.

Gold standard battery if it fits your plane. Just replaced one that turned 6 years old on my I0-540 / Saratoga. It was still cranking just starting to show some signs of weakness. Only negative is that it’s gone up quite a bit in price over the last 6 years, but let’s face it, so has everything else.

The new battery is working fine. Sadly, the previous one from Concorde cost much less. That one lasted about 7 years.

Michael R Verified Purchase

CONCORDE SEALED BATTERY RG-35A

Excellent battery. Last one lasted 7 years of being abused by the previous owner (not flying it or charging it and letting it freeze dead repeatedly). SInce the last owner didnt log the battery installation, Concorde helped me determine its age via the serial #. Quickly and happily. Price is ridiculous, but for ~$75/yr its not bad. Hopefully the next one will last longer with the BatteryMinder on it.

William A Verified Purchase

CONCORDE SEALED BATTERY RG-35AXC

I ordered two of the same sparkplugs , when I checked them, one of them had a gap a little tighter than I wanted , I was able to adjust but it would be easier to close a larger gap than one you want to open . Thanks Joe

TEMPEST SPARK PLUG UREM40E

These Concord batteries are simply terrific. We began using both the 25s and 35’s , particularly the RG-35AXC in float planes and have found them to be reliable and trouble free. - even up to five years use. The most recent purchase replaced a five year old Concord but it had been left in the aircraft in an unheated hangar over winter with no trickle charger supporting it. Not the batteries fault it this case. While we don’t sell as many batteries as normal the customers are pleased. Mike

Carrizozo A Verified Purchase

TEMPEST SPARK PLUG UREM40E

Nice to know that its sealed, and has significantly better performance over a regular lead acid battery. I havent had this very long so I cant comment on its longevity, but it cranks the plane much easier.

GILL SEALED BATTERY 7035-28

This battery is a great product, and Aircraft Spruce is a great company to do business with. When I ordered my battery, I was told it was out of stock, and I could not expect it until June 1st (a 6 week wait). Spruce went and found me a battery, and I received the shipment in 3-days. You cannot beat the service. Thank you Spruce.

Concorde batteries are excellent and their factory support is top shelf. I ordered this particular RG35A to replace an identical unit that held up well for 7 years. Not too shabby.

Only use tempest plugs anymore. Less money and no resistance problems. I wish they galvanized them though as they rust easily on the outside. Clear coat paint before install might help.

Replaced my RG-35 with the RG-35AXC. First one lasted almost 10 years, never let me down once. The old one was finally getting weak so I was sold on buying another for my C182 and decided to get the extra cranking power of the AXC. Worked great right from the box.

Randy S Verified Purchase

I previously installed these in the lower plugs in an IO-540 engine to eliminate lead fouling. When the standard plugs in the tops needed replacing I upgraded to the Tempest fine wire plugs. The engine now runs noticeably smoother and the mag drops are minimal. I also noticed a drop in EGTs during takeoff. I recommend these spark plugs.

I bought the fine wire spark plug. To put in the bottom of my cylinder 3. Although the compression still reads 71 it seems to pump oil on that bottom plug. I have only put 4 hours on it so far. But performance seems to be the same as the massive one. I change oil and rotate plugs every 25 hours. I’ll let you know.
