We always try to recommend the best possible spark plugs for the money, and these spark plugs are either a factory recomendation or an equivalent replacement available now at an affordable price.

How often should I change my spark plugs?

Very generally, it is advised that you replace spark plugs once every 20,000 to 40,000 miles. Of course, please make sure to check your owner’s manual to determine the exact interval determined by Chevrolet for the 1998 Tiltmaster. Of course, if you drive your vehicle more aggressively or own a Tiltmaster with some modifications, you may want to consider changing your spark plugs closer to the 20,000 miles end of that spectrum.

However, there are also telltale signs of a car that needs a spark plug replacement earlier than the recommended schedule, such as:

  • Engine misfiring
  • Rough idle
  • Problems starting your engine

Note that this list is of course not comprehensive, and these problems on their own do not definitively point to the spark plugs being the solitary culprit. However, the best way to prevent any issues with your vehicle is to take care of it with routine maintenance, and you are definitely doing so with the responsible decision to replace your Chevrolet Tiltmaster’s spark plugs on a regular basis.

Helpful Tools

A set of spark plug sockets is extremely useful. Certain spark plugs and engines make this job impossible without one
As noted before, you should be able to accomplish a spark plug change with some regular tools you probably already have. However, there are a few tools that are specific to this job that you may not have, and we also want to recommend some commonplace tools that you should absolutely have in your toolbox if you do not already.

  • A spark plug tester – this is definitely a niche tool, but it can save you lots of time. Although we’ve discussed spark plug replacement being a good thing to replace regularly and not just when issues occur, you may also be replacing your spark plugs because of something going wrong. This tool can help you diagnose the definite problem.
  • A set of spark plug sockets – These come in extremely handy because many standard sockets are not deep enough for spark plugs. Additionally, some spark plug holes are a bit smaller, so it requires a thinner wall like the one featured in the product here to fit. The linked product also features a magnet to keep a good hold of the spark plug so you do not drop it into your engine bay!
  • A torque wrench is a very important tool to have in your arsenal. You will want to check your factory service manual to determine the correct torque rating to use when inserting the new spark plugs for your 1998 Chevrolet Tiltmaster to be confident they are installed properly.
  • A spark plug gap tool. This allows you to check the gap of your spark plugs and modify it if necessary. Most plugs will come pregapped, but if not, you should absolutely have one of these.

Be sure to review the video above before you attempt to repair the spark plugs on your 1998 Chevrolet Tiltmaster, as well as review your factory service manual. Also, see the tips included below here to help you as you complete this repair.

  • During this process, one of the most vital things to ensure you do is to avoid overtightening the plugs or worse, cracking them due to overtightenting. Use a torque wrench capable of lower, more precise torque ratings to be sure that you don’t make this mistake.
  • Before starting, disconnect the negative terminal of your battery. It is wise to disconnect the battery anytime you work on the electrical system of your Chevrolet Tiltmaster or any other vehicle.
  • Note that this is not official advice as many spark plug manufacturers advise against the use of anti-seize. However, I have heard from numerous old-school mechanics that they always apply a small amount of anti-seize to the threads of their spark plugs, especially on older vehicles.
  • Your engine should be cold before you replace your spark plugs. Wait at least 30 minutes after any kind of operation before attempting to replace the spark plugs on your 1998 Chevrolet Tiltmaster
  • It isn’t a bad idea to use dielectric grease when installing new spark plugs. You can apply a a very light coating to the inside of the boot and the ceramic part of your spark plugs. It prevents voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
