In one sentence, describe what the following article is about: Whether you're shopping for new plugs, you just bought new plugs that you want to check before installing, or you want to check the function of your current set of spark plugs, you need to learn the appropriate gap between the two electrodes on the end of each plug.  Each vehicle's measurement will be different, though most are generally somewhere between 0.028-.06 inch. You can either look in your owner's manual or go to the auto parts store and have them look it up for you. Modified engines require smaller gap settings to account for the amount of power you're putting through the engine. General rule of thumb: the more power, the smaller the gap. There are several varieties of tools used to measure the gaps of spark plugs, some of which are more appropriate for more modern plugs, which sometimes feature delicate precious metals. Most measuring tools will also feature a flat edge typically used for bending the bottom electrode on the spark plug to adjust the gap slightly.  A coin-style gap measure is usually the cheapest option, and works by running the edge of the "coin" through the gap until you reach a point where it stops. The edge is marked like a ruler, designating the thickness of the edge at that point. This is a good tool for older plugs you want to check the efficacy of, but can also inadvertently widen the gaps as you use it. A wire coin gap works essentially the same way as the regular coin-style gap, but features different wire measures of varying lengths on the edge around the coin. A blade-style feeler gauge is an effective and versatile tool. Built like a pocket-knife, this gauge features different blades of varying widths, some with wire on the end and some without, placed in the gap to check the spacing of the electrodes. You can also use multiple blades to measure larger gaps. These are effective to use while adjusting. . If you've just pulled it out of the box, it should be in pretty good shape, but if you're checking a plug that you've been using in your car it's a good idea to clean it off a little with a clean cloth. Spark plugs can build up some whitish soot on the contact points, so you'll want to make sure they're somewhat clean to get the most accurate reading. You can use a little bit of quick-drying (90%) alcohol on the contact points to clean them off if they're especially dirty. Lots of build-up or any blackening on the contact points might be a sign of a plug that's outlasted its prime, however. If they're especially dirty, you might consider buying new ones. Place the appropriate blade or wire on your gap tool between the electrode tips of the plug, or pass the coin through the electrodes to determine the measurement.
Summary: Learn your vehicle's gap specifications. Select an appropriate gap tool. Clean the spark plug Measure the gap by passing the tool through the electrodes.

In one sentence, describe what the following article is about: High flavonoid foods have anti-inflammatory properties, which may help with your allergies. These same foods are high in the substances quercetin and rutin. Quercetin and rutin are natural antihistamines. High flavonoid foods include:  Berries Red peppers Citrus fruit Bananas Pears Apples Onions Almonds Leafy green vegetables Olive oil Green tea Herbal teas such as parsley, nettles, and sage Some naturopaths believe that a weak immune system may make it easier for allergens to affect you. Incorporate some daily supplements into your diet to help strengthen your immune system.  Add a multi-vitamin. Find a high potency multi-vitamin and take it every day with food and a glass of water. Add probiotics to your diet. Have one container of yogurt (with active cultures) every day or take a probiotic supplement Add Vitamin C to your supplement list. Vitamin C is another antioxidant and can help reduce reactions to allergens.  Add Omega-3 fatty acids. Omega-3 fatty acids are anti-inflammatory agents and can help to reduce the symptoms of allergies There are several different herbs that may help you to prepare for allergy season and reduce your symptoms when the season arrives. Talk to a knowledgeable healthcare professional first, especially if you are taking any medications, including antihistamines.  Herbs can either increase or decrease the effects of some medications, so it is important to check with your physician first.  Dong quai (Angelica sinensis) Eyebright (Euphrasia officinalis) — especially for allergic reactions affecting the eyes Stinging Nettles (Urtica dioica) Quercetin and rutin can be taken as a supplement, usually starting six to eight weeks before allergy season.  Don't take quercetin or rutin if you have liver disease. Exercising for 30 minutes three to four times a week has been shown to be effective in reducing allergies. Exercise indoors on high pollen count days and take precautions to reduce your exposure to allergens on days that you exercise outside.  Swimming in chlorinated pools can make allergies worse.  Listen to your body and be aware of your symptoms. For some people, exercise may induce allergies and asthma attacks.
Summary:
Increase your intake of high-flavonoid foods. Take supplements to help strengthen your immune system. Consider using herbs as teas or as supplements. Get moderate exercise.
